Consolidation or Fully coupled flow deformation for excess pore pressure variation due to line drain
Which of the above analyses is better for finding the variation of excess pore pressure with radial distance from a line drain?
Excess pore water pressure is non-zero at the soil-drain interface
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…
Line drains and varying permeability in the horizontal direction in a soil model
I am trying to simulate the effect of the installation of PVDs on soft soil (soil model used: MCC). The installation of PVD (in this case, a line drain) causes disturbance to the soil and creates three zones around the soil. A smear zone, a transition…
High excess pore pressure at particular nodes during consolidation analysis in Plaxis 3D
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…
