Regarding thread256-468265 : mar2805, the formula you are using also comes from Terzaghi's book, p. 124. The answer to your inquiry is detailed in the book Bowles Foundation Analysis and Design, p. 222 & around it.
The book has a very comprehensive explanation, so I won't repeat it here...
Hello, I am a civil engineer and I have several threads posted in the geotechnical forum, so I am not an automotive engineer or know anything about the subject, but I have a problem and I thought somebody in this forum could suggest something useful to solve it.
I have a 2002 Dodge Stratus with...
Thanks for all the very useful replies! I will definitely check LittleWheels' link detector, just hope it isn't too pricey... I wasn't expecting the advice on the divining rods [lol], I am usually on the skeptic side of things... but they're cheap so why not give them a try... TigerGuy I feel...
Does anyone know how to locate buried pvc water pipes or sewage concrete pipes underground so to not hit them when excavating with a backhoe?
GPR could be useful, but besides being expensive, I understand it doesn't work on clayely or moist soils. Last time I checked, most soils here are clays...
Ok. That "some phi" (in totals), What is it used for in calculations? You are supposed to check undrained conditions with Su and phi = 0º, and drained conditions with c' and phi'.

How do you saturate soil specimens for UU triaxial testing or UCS? Assuming they are partially saturated.

OldestGuy, Ron, epoxybot I will read the books you mention. MTNclimber, I think that there must be more geo-forensics books out there… hidden :) If I find some I will post here :)

Has anyone read a very comprehensive book about geotechnical failures that have happened in the recent, real world? Common failures, rare failures, failures the regular geotechnical books don't say nothing about, structural failures blamed wrongfully to the soil, sinkholes, cases like the...
Hello everybody. I am writing this post related to the thread158-157942. in which there is a confusion about the sum of two quantities on the equation for correlating LL, w and density to the swelling pressure of the soil, which appears on Bowles Foundation analysis and design 5th. edition.
A...
Yeah, I've seen those powerful saws with carbide teeth; I may try them sometime in the future, but not right now because those would be useful specially with hard clay shales or sandstones, and I work mostly with clays and sandy clays.
But, yeah I don't know if a powerful chainsaw or other tool...
Some years ago, I found a very interesting publication in the ASTM website. It was about the use of a chainsaw for obtaining undisturbed cubic samples of soil for triaxial testing. It interested me, because obtaining such samples is very labor and time consuming and I've always searched for...
Well, I agree with your comments and it's nice to know we share the same engineering judgment [smile]. I normally calculate the elastic settlement (with a very high modulus of elasticity, the SPT samples are very hard) and assume there will be no considerable consolidation. I can't find any...
Hello, I am new to the forum, but I've had my geotechnical lab for several years now. I have a doubt which I hope someone can solve: Can a clay stratum with N SPT > 50 be considered incompressible regarding to consolidation settlement? Thanx beforehand.
