How can i model the reinforced zone above a tunnel crown with umbrella pipes in MIDAS GTS NX??

24 January 2021 1 3K Report

I am using MIDAS GTS NX to simulate an urban tunnel excavation with NATM method, the tunnel wizard option in the program allows to simulate the rockbolts but it does not allow to model the pre-reinforcement of the umbrella pipes.

should i create it manually or simualte it by inclined rockbolts !

has anyone done this model before ?

I recommend you to model the umbrella pipes in a cad software, and then import it into MIDAS GTS-NX. It's easier than you think.

There's a video about this in MIDAS' YouTube channel: https://www.youtube.com/watch?v=ZHi_A6aJM88

Hope this helps you.

Bye, Felipe.

what is the simplest definition of ion exchange capacity

What this unit identifies for the ion exchange capacity ca. 0.92 meq. g-1. I am a newcomer in the membrane area. I just started. I highly appreciate your help
