Hi, May I please receive some assistance with the following query, I've been attempting to simulate laboratory oedometer tests using the Soft Soil Creep Model and the Soft Soils model and found that the curves don't seem to match. Please refer to…

Hi, despite running a consolidation analysis using steady state ground flow calculation type the excess pore pressure won't dissipate. The ground stratifacation is as follows: Backfill followed by upper clay layer, sand in the middle and a clay layer…

Hi, I am using the soft soil creep model to predict the settlement due to consolidation and creep for a foundation. I am wondering whether it's necessary to introduce an intermediate (dummy) phase with large time interval after the initial conditions…

Hi everyone, I am working on a consolidation analysis using the Soft Soil Creep model to assess the long term settlement of a deep, normally consolidated clay layer due to the load of a building. I calibrated my const. model parameters based on a consolidation…

The problem is concerned with staged construction of embankment. While trying to plot excess PWP vs time, the results are not matching the expected outcome. Is it because of the alternate plastic/consolidation calculation type? If so, how can I produce…

Hi all, In MC model, the excess PWP calculation is not correct and Cv term is calculated automatically in MC model based on input values Eoed (E and v') and k. Disregard these let's say I'm using MC model for the consolidation analysis without using…

Hi all, There are 3 types of variation of excess PWP due to increase loading in the undrained soil as shown below. 01. The uniform variation can be obtained from the uniform loading as shown below. 02. high on top side and loa on bottom side…

Which of the above analyses is better for finding the variation of excess pore pressure with radial distance from a line drain?

I installed a PVD (line drain) on MCC soil model and completed a consolidation analysis. In the output, the excess pore pressure at the drain is non-zero. I have used very fine mesh for this study, taking the smallest element as possible. How can I make…

In PLAXIS V20,V21 and V22 there is included PVD drain. But How can I simulate Stone column in PLAXIS 2D v21 ?

Hi, I am getting very high excess pore pressures at particular nodes beneath the pile cap, adjacent to the embedded beams as shown below,. This is causing very slow convergence and excess pwp is not changing after particular point. (fig 1 - phase before…

Hi, the option for consolidation analysis does not seem available in the calculation phases, only plastic and phi-c reduction. Not sure why this is? I am trying to model heave over time due to an excavation in clay. thanks

I am attempting to complete consolidation analysis using "alternatives" primary and secondary consolidation coefficients, however, every time I exit the model and enter again it reverts back to lambda and kappa. It seems like if I stay in the model it…

Hi all, I've inherited a model from a consultant of a staged excavation in saturated, stiff clay that is expected to behave undrained. Once the excavation goes below water table, each stage was given a Plastic calculation (0 days) and a Consolidation…
