I need to study the dynamic non-linear response of reinforced soil wall with anchors. Hence, I used structural beams for reinforcement and structural bars for anchors. However, there was error in the model which displays "Structural beams and bars cannot be specified with a non-linear analysis in QUAKE/W" What can be done…
Hi All, I have a seepage model in SEEP/W where I am modeling a seepage flow due to storm surchage for a coastal flood wall. I'm looking at steady-state analyses (as an upper bound/worst case scenario with prolonged max flood water elevation) as well as transient analyses (with water surface rising/falling with storm and…
I have two approximately identical slope/w models of an existing earthen embankment dam with different factors of safety. Both models consider a failure of the upstream slope of the embankment. The only difference between the two models is how the approximately same phreatic surface is input. "Model 1" has a phreatic…
For the stability analysis of embankment dam, what should be the direction of horizontal and vertical seismic coefficient. 1.What is the meaning of a positive and negative coefficient for both vertical and horizontal case? 2. For eg. for the stability analysis of embankment dam for d/s slope what should be the sign for the…
When I run my stability analysis with an anchor, it is showing that the support from the bonded zone is in front of the critical failure surface (as shown by the red box). When I make the anchor longer, this support goes away, which seems to me the opposite of what should happen. What is going on?
Hello, In the case of a levee with multiple rows of anchors embedded in chalk, I perform a stability calculation by imposing a failure plane. My slope calculation does not converge (E994). I have tested different approaches: linear search and root finder. In the convergence graph, lambda never exceeds 0.2. Can it go beyond…
Hi for All. SIGMA W visualise only total pore water pressure. How can i get and visualise the excess water pore pressure ?????
Hi I have created two steady-state 2d groundwater models without and with an excavation and a drainage layer. I would like to compare these and get the difference in water levels/pressure. I cant really seem to find any way to do this so I would really like to hear from the expertise here. Best regards
Hi, I am modelling construction of a capping layer on top of the tailings. I use saturated model for tailings and unsat model for capping material. When I applied the first layer of capping layer, I get another water table at the top like a perched water table. I even use very low activation PWP and compressibility for…
Dear all, Is it possible to implement a user-defined constitutive model into Geostuido SIGMA/W? If yes, then what programming language is supported? Are there any examples for reference? I'd appreciate it for your help. Regards Chou.
