Classical slope stability analysis includes both: Effective Stress analysis (ESA) for obtaining FOS for long run and Total Stress analysis (TSA) for obtaining FOS for short run.
For TSA I use undrained strength parameters obtained from CU triaxial test. When performing TSA (one phase analysis) I...
In the same analysis step I have a surfec on which the temperature is prescribed as a BC , on the same surface I applied loading : heat flux. I expected the job to be aborted as two fields that are cojugate are applied on the same surface, but the job continued running. How that could happen...
I want to test my slope model sensitivity to a hypothetical extreme rainfall event.
Is an extreme precipitation event represented by a daily rain amount of 50 mm over 3 consecutive days realistic in Canada and /or the US regions.
Please refer me to a refernce (if possible). Environment Canada...
I have developed a model for simulating the hydromechanical behavior of landslide .
I assume a hypothetical landslide and I want to test my model sensitivity to a hypothetical extreme rainfall event.
Is an extreme precipitation event represented by a daily rain amount of 50 mm over three...
Your advanced analysis shows that all points of the soil under your foundation will settle and non uniform settlement curve is observed ; say look like a half or quarter circular shape (depending on the load of the foundation).
How the total settlement usually assessed:
Do you take an average...
Is this the right erosion mechanism explination ? Please advise:
The differential settlement along the base of a highly compacted sand dam will result in a vertical crack breaking up the dam. If the internal compressive stress is not high enough to squeeze the crack shut, it will remain open...
: When analyzing clayey soils under earthquake
which shear strength we should use (in principle):
A) Residual undrained shear strength or
B) unconsolidated undrained shear strength obtained from the unconsolidated undrained traixial shear
One can get Mises in ABAQUS as a areadily avialble output but I noticed that one can not readily obtain the deviatoric strain (the Mises stress-work conjugate)!!!!!!!!!! and in this case one has to compute it. Plesae correct me if I am wrong.
Whenever I heard the word "TENSION" in the geotechnical business or read it in any text book I start to get confused.
-Sometime it implies the existence of cohesion which means that soil can bear a negative confining stress.
(Vertical cut which is subjected to tension: is sustained because...
I have created a new field output can any one tell if plotting this field output with time is possible (like what I do with other output exixting in the model).Can one do Operate on XY operations on that field output. I couldnot figure it out from the Documentations
If any of you familiar with Slope/W:
I have a simple question but yet puzzling
If you want to locate a point (for example when you drowing a slope geomtry) you have to move the cursor until finding the right coordinates of this point (this is really hassle).
Is there a way where one can locate...
Hello
The Documentation materials related to some models (like Drucker-Prager) implies that softening can be used under each of
*DRUCKER PRAGER HARDENING
The classic meaning of softening is that your Yield Stress starts to decrease while your Absolute Plastic Strain Rate is still increasing...
Good day ...
My single part model has different materials . After plotting the contours I cannot distinguish anymore the borders between these materials . This is very important to interpret the result. Is there any way to show these borders (edges seperating the different section forming this...
I plot the results along a profile (path) taken through my model (as a Y axis). But I want to view (display) these results on the model itself so that the the person looking at the model sees clearly and directly on the model where exactly this plotted response is .
I have found that using...
Hello All
I have done staged construction deformation analyses of earth/tailings dams using advanced numerical modelling ( no ready FOS can be given) . I can get all kinds of output(related to hydrology :pore pressures,saturation, flow velocity.. and mechanical outputs: stresses , strains...
Does any one know how we apply fluid infilitration (Influx)through a surface?
I am using Pore Fluid Force which should lead to increasing the addition of water into the system and thus raising the water level within the system but that doesnot happen. Instead, the water level decreases upon...
I am getting this message . Does any one know why and what is the solution to this:
***WARNING: THE MEAN NORMAL STRESS IS ZERO OR POSITIVE FOR ELEMENT 1068

Hello
Can anyone of you guide me to guiding listing the alloawble settelement/deformation for the geosystems (piles, shallow foundation, embankments...) and the recommended minimum FOS for different geosystems (FOS against liquefaction, slope FOS, FOS against bearing capacity failure and so on)
I am doing deformation analyses and trying to adopt a criterion for my slope failure based on the deformation amount. Is any one of you aware of an allawable value of the deformation of the slope that is given by a code or guidance/recommendation of specific practice.
Thanks
