If you have earth dam composed of low permeability soils and this dam is exposed to flood , it should shear under undrained case. However, in most practice earth dams and levees are usually analyzed considering undrained shear only when they are under rapid drawdown case. Why the undrained...

- Is anyone aware of on-line spreadsheets doing the calssical geotechnical computations: bearing capacity, consolidation, earth pressure, mass-volume relationships, and other classical geotechnical formulas.
I am very clear with the underlying formulations and the philosphy on which these...
Retaining walls are guarded against overturnning by taking the ratio of the driving moments/resisting moments.
all around the toe.
But I noticed that driving moment of the force resultant of the effective vertical bearing pressure at the bottom of the wall (which is equal to the sum of the...
1-You get the undrained shear strength from the Vane shear test. Is this equivalent to the one we get from the undrained unconsolidated shear triaxial test.
If yes , which one does it represent.? the peak or the residual one.
2-By the way, can any one refeer me to a source where shear...
Hello my friends,
I am looking for a quick tool ,for example ,excel-sheet , for calculation of settlement of embankment on clayey soil just to have a quick felling on “what-if “ concerning the settlement of my embankment. Thanks a lot for support.
Does Triaxial Shear Extension test imply that the deviatoric stress q =(Simga Vertical-Sigma Horizontal) is negative or the change in deviatoric stress q is negative..?Or both.?
I know that when the change in q is negative (q decreases) while q still positive means unloading.
When would you...
Hello guys
A head person in my company has asked me to go and inspect a big tailings dam in remote site (interim preliminary inspection to ensure safety for a short run). "Direction by telephone could have been provided to me" the person said
I have never inspected such kind of huge structures...
Hello
They have a proposed location for a building (5 floors).
Not to far from the proposed site there are controlled explosion activities going on (Quarry source). I want to comment if siesmic activities impact the foundation location.
Plesae advise on some practical materials associated with...
Your geological map shows that you have a fault crossing your rock slope contour lines. If I want to consider a slope cross section for analysis for plane failure then what is the most dangerous cross section to consider as far as the fault is concerned. I believe that the section parallel to...
am conducting a rock stability analysis:
On the geological map I have only coulpe of lines each shows one fault. I projected these lines on the topographic map and I can see that one line is intersecting the slope contour and another is parrelle to the slope countors. My quesions are:
1-...
I have the topographic map showing the slope geometry and couple of intersecting faults existing in the slope region.
In order to perform failure potential for wedge and planner assessment. I only have topographic map showing the slope on which the faults are plotted and rock strength data...

I am doing a water-pressure test on U pipe installed 200 m within the ground ( for heat source pump system).I applied a pressure of 700 KPa . However, the pressure after 9 hours drops to 650 Kpa. The temperature is not less than 1 degree. Does that indicate leakage? Is it acceptable
