PLAXIS 3D Tunnel crossing with volume elements
Hi all,
First question here :) For a project I'm working on I am modelling a set of access tunnels used to allow construction of an underground structure (in PLX 3D 22.02). Starting out from an initial 2D project which works well I tried extending the…
Tunneling - Sequencing Tunnel with pilot Tunnel
Dear Ladies and Gentlemen!
I want to model a NATM Tunnel with a pilot Tunnel in Plaxis 3D.
At first a pilot Tunnel has to be build over the whole length. After this the "normal" tunneling starts.

Error code:111 in modelling of a NATM Tunnel in PLAXIS 3D
Dear Soilvision Forum,
I'm currently working on my diploma thesis and I'm modelling compensation grouting above a NATM tunnel. The tunnel is only a part of the thesis to cause settlements for the compensation grouting.
After a preheaving phase the…
Tunnel advancement
Dear Sirs,
I want to model a tunnel constructed in the NATM with PLAXIS 3D. For example, the excavation for the bench should have twice the length of the excavation for the Top-heading, or the excavation of the heading should be like this: one meter…
