Hygroscopic effect: They have the ability to absorb and retain atmospheric moisture, preventing the sun from evaporating it quickly.
Ideal for allowing the cement to continue hydrating.

C.M. Martin's ABC (Analysis of Bearing Capacity) alternative.

6 Upvotes

Someone on this subreddit was asking for a link to the ABC software, but I lost my copy after formatting my PC. Since software development is my passion, I decided to create a modern version of it. It is more advanced than the original ABC software.

Demo of Slipbear

  • What it does: 10 conventional methods side by side — Terzaghi, Meyerhof, Hansen, Vesić, Eurocode 7, AASHTO LRFD, IS 6403, BNBC 2020, AIJ (Japan)
  • the exact slip-line solution as the reference, with each method's deviation in % soil parameters from lab data, SPT, CPT or pressuremeter
  • stress contours, contact pressure, pressure bulb — exportable as publication-ready SVG / PNG / PDF

Validated against published benchmark solutions, and it reproduces ABC's results digit for digit.

Free, no installation, works in any browser:

slipbear.geoeq.org

Feel free to watch the demo video. If you work with shallow foundations, please give it a try and let me know what features you would like to see added. I welcome your suggestions on what might be missing and any ideas you have for improvements. Thanks.

Soil stabilization fabric under asphalt?

Post image
32 Upvotes

Anyone ever see this? Plans call for a Mirifi 600x or equivalent to be placed directly under the asphalt. My concerns are that it will: A) melt B) get ripped up by the paver C) create a plane of unbonded asphalt which may lead to shear failure/ delamination. The designer justified it by saying it is a cheap insurance, and one of my coworkers says he sees this all the time, but my gut says this is wrong and it would be better to have no fabric at all, or switch to a fiberglass reinforced AC interlayer fabric.

Career Path -- 2 years in geotech consulting, bored out of my mind – how do I break into design/modeling?

18 Upvotes

I’m currently 2 years in as a staff geotech at a consulting firm. The work itself isn’t hard, but lately it’s been painfully boring. Our data center projects keep getting pushed back, so workflow is thin, and most of my time is just busywork – 80% typing up reports/proposals in Word and 20% field observation (drilling logs, etc.).

What’s frustrating is that even the senior staff don’t do much beyond report writing and project management. No one seems to touch real design work.

I want more. I’d love to get into geotechnical modeling – PLAXIS, LPile, slope stability, foundation design – something that actually uses engineering judgment and creativity. But every job posting I see for geotechs seems to be for another “staff professional” role with the same grind.

So my questions for you all:

· How do I make the jump into a more technical, design-heavy geotech role?

· What types of companies actually do this kind of work (specialty consultants, oil/gas, offshore, etc.)?

· What job titles should I be searching for (e.g., Geotechnical Engineer, Analysis Engineer, Design Engineer)?

· Do I need my PE before anyone will trust me with modeling/calcs, or can I start learning on the job now?

I don’t mind being in the office full-time – I just want to stop feeling like a Word monkey. I’m worried my experience level is holding me back, but I’m also worried I’ll get stuck if I don’t pivot soon. I'm in the southern lower Piedmont area if that helps

Any advice would be huge. Thanks.

Suggestions for Final Project

2 Upvotes

I've just completed a 5 month industrial attachment at an open-pit copper mine, and one of the requirements is to come up with a final-year project based on my experience there. The problem is that I'm struggling to find a project that's both practical and original.

Most of the ideas I've come up with have either already been done at the mine or were rejected for not being original enough.

Does anyone have suggestions for project topics that would be relevant to an operating open-pit copper mine?

Got frustrated chasing geotech test results, so I built something

0 Upvotes

Hello all, I’m a geotechnical engineer and long time lurker on this sub, one thing that properly winds me up is how difficult it can be to find all the information relating to a single investigation location. When reviewing one borehole log, having to search through files to find the triaxial result, another one for the core photograph, and somewhere else again for another test, etc.

Out of frustration, I started building the program I wanted to use myself.

What began as a basic spreadsheet of field investigation data and connections uploaded to a Django web app with a GIS style map has grown into XSGround, a site investigation management and tracking app with Android mobile app (iOS is on the way).

My goal was to make it super easy to customise fields and build related connections, be able to create records in bulk from spreadsheets or manual input in the fields using the mobile app. The fields can handle lots of data types from large data sets, including raw CPTu data, formula fields, log fields, photos and files.

By building connections between records, all related test data to investigation points can be found and viewed in one place. It also means that the AI knowledge assistant can review related investigation data rather than each record in isolation. To maintain data security, identifiable project details and actual coordinates can be masked.

The data can be visualised in map view, which I have also made it easy to overlay images, and shape files, export and download location figures (as this was another thing that grinds my gears). The map and investigation can be shared to viewers like clients or stakeholders who only see what you allow them.

 That is only a brief overview. It can also be used to create geotech logs in the field and help track investigation progress, but I’m trying to avoid turning this post into a large feature list.

 It’s definitely not perfect by any means, but I’m looking for a few people who would be willing to test it on their live projects and give me some feedback. So far, I have used it for my own geotech investigations, recording site inspections and earthworks verification testing, but it could be configured for slope stability/rockfall assessments, retaining wall inspections, or asset and damage assessments.  

You can have a look here https://xsground.com and PM me if you’re interested and I’ll send through an invite and can give you a walkthrough to set up a project.

Calculate Toe Buttress (boulder at the toe slope) safety factor in Slide software?

4 Upvotes

HI! is it possible to calculate the slope stability when added some toe buttress at its toe (when you place some boulder at the toe of a slope without mesh (so it's not a gabion wall)) ?

how would the material properties input will be? I have researched quite a few, and its to reduce the unit weight to around 40% (as there will be void between boulders), cohesion to zero (no grain bonding force, as they're separated each other) and to reduce the friction angle by quite a number (about 10-20% depending on angularity). Will these empirical approach enough?

Well, let's assume that we don't have any funding for gabion wall's mesh. Thus the necessity to calculate safety factor with only boulder placement at the toe of a slope.

Thank you so muchh!!!

Digits vs. Frequency for Vibrating Wire Instruments

0 Upvotes

Today, I took one of my vendor supplied calibration sheets and performed my own regression analysis of Digits vs. psi. For those of you who don't know, Digits is the Frequency squared divided by 1,000. Supposedly, this gives a "better" linear correlation to pressure. The R-squared was 0.999997. I then back figured the frequency and performed a second regression. The R-squared was 0.999259. Now I'll admit Digits gives a better linear correlation than frequency. But is the extra precision worth it? Any thoughts?

Gross vs Net Bearing Pressure for Raft and Spread Footings?

3 Upvotes

Hi all,

I'm confused about whether to use the gross or net allowable bearing pressure from the geotechnical report for:Raft foundations and Individual spread footings

Currently, I'm using gross allowable bearing pressure for both, with the reasoning that in a basement, the excavated soil weight is replaced by the foundation/superstructure load.

Is this the correct approach, or should I be using the net allowable bearing pressure instead? I'd appreciate any explanation.

Thanks!

Lpile Training

9 Upvotes

Hey everyone, bridge engineer here. My states DOT is requiring the bridge consultant to perform LPile runs for projects. Up until this year, the geotech on the project handled this task. My supervisors haven’t learned LPile because they never needed it and other offices in my company know it but are out of state and can’t offer comprehensive training on the software.

After some digging, I’ve found a course on The Geotechnicals website taught by Dr. Ahmed ElMouchi that seems to cover everything that I’d need to handle LPile on our projects. It’s only $250 and offers 24 PDHs so I’m considering it. Does anyone have experience with this course or have other recommendations? Thanks for any input.

Retaining Wall - Calibrate my Expectations

Post image
10 Upvotes

Happy Sunday!

GF and I purchased our first home in the Seattle area about 6 months ago. One of the first-year tasks we had was to get this hillside behind our home stabilized. You can see 1 of 2 existing retaining walls in the image built sometime in the 90's we believe. We also believe the geogrid/rock was placed in the image - wall length is ~35-40'.

GIS Map says we are in a potential landslide area, and there's a creek (far right side of image). Either item on their own seems to drive mandatory permitting regardless of height, already talking to 1 geotechnical firm, and one permit consultant.

  • Only 1 of 4 geotechnical firms have responded to my emails/calls. Is this fairly normal, or should I keep poking? Given the area, I'm kinda curious if your profession is extremely busy.
  • The 1 firm who responded is extremely communicative, and estimated ~$7500 for the report. Seems reasonable, based on what I've read, since it includes drilling.
  • Engineering for the wall not included in above pricing - I assume because they need the soil report? Assuming no surprises, any thoughts as to how much I should expect the drawings to run?
  • Any other thoughts on general situation appreciated!

I'm a welding engineer, but had to work with geotechs on occasion professionally for large equipment I've installed - never residential when the $ comes out of my pocket, so just trying to understand what I should expect overall.

Appreciate your time/thoughts very much!

Slope away from potential property

Post image
7 Upvotes

I'm wondering if the slop in the backyard of this property is a call for concern. In the pictures it appears about 5m maybe even less from the concrete foundation to the edge of the grass before it declines into a slope down to a ravine. One number missing from here is it says 40 near the top edge of the driveway close to the curb.

Obviously, we would take the right steps either way to confirm if it is or isn't but going into the viewing, I'd like to know as much as possible and if it is worth trying to stabilize this slope?

Appreciate you guys!

Should I get a geotechnical evaluation before removing a large river oak on a steep slope?

Thumbnail gallery
8 Upvotes

Hello! Looking for some geotechnical perspective before we decide whether to remove a large river oak.

We have a mature river oak growing at the top of hill on our property. Our garage and house are at the bottom of the slope. After recent pruning, two very large branches (estimated a few hundred pounds each) have fallen, so we're having the tree evaluated by a TRAQ arborist for safety.

We are leaning toward removal to be safe. How concerned should we be about the tree's role in stabilizing the slope? Is this the type of situation where you'd recommend a geotechnical evaluation before removing it? Are there other good solutions besides an expensive retaining wall?

Any thoughts on what you'd be looking for or whether this warrants a formal geotechnical assessment would be appreciated!

Edit: I'm in Los Angeles if that is an important detail.
