About Tunnel analysis outcome
For example, when we finish a NATM Tunnel Analysis, how to find the Support Pressure at the end?
NATM Tunnel Analysis in Plaxis 3D calculation error
I am doing a NATM Tunnel Analysis in Plaxis 3D, but when everything is finished and the calculations are given, it shows a problem in phase 01 like this. (Soil body seems to collapse. Please inspect Output results. [Error code: 101] ) What is the reason…
Deconfinement vs Mstage
Hi guys,
Just wondering whether i) Mstage method or ii) deconfinement method to be adopted for NATM (taking steady state flow calculation into account)?
