FLOW ANALYSIS IN PLAXIS 2D

Structure User — Thu, 03 Nov 2022 09:23:56 GMT

Hello, I am performing a rapid groundwater level drawdown around a tunnel using a steady-state flow analysis in order to predict the settlements due to dewatering of the tunnel.

Although the input-ouput file seems to work fine, I am getting a lot of settlement due to dewatering at the model boundaries and it seems that the settlement trough covers the whole model and that the GWL is modified through out the whole model. According the flow theory no change in GWL and pore pressures takes place outside the hydraulic radius of the tunnel. (For the assigned permeability this is about 50 m). I am feeling that I am missing something so I would like to ask: Is there a special boundary condition I should use, to prevent this phenomenon ? I would like the GWL to remain stable (no modification) in pore pressures at model boundaries.

Connectivity plot

Is there an easy way to obtain connectivity plots in an automatic way using commands ?

I am trying to show the geometry of the different stages / phases of the model.

Thank you

Hello, I am trying to obtain plots using the python script "Export and format plots from PLAXIS Output using Python" but it doesn't seem to work in my case. I get the message: name 'g_o' is not defined. How could I make it work ? Tha

NameError: name 'g_o' is not defined.

Should I remove it ?

I am not at all familiar with Python.
