Can you please give me a guide on shield tunnel modeling

[[email protected]]

Dear STKO

I am a beginner of STKO software

My research direction is seismic response of shield tunnel in liquefied ground

At present, I have been able to build a free field model independently, but the part of building a shield tunnel in the soil is not very good. What tutorials or videos can help me learn?

Dear user,
try to put here some details about how you would like to proceed to build the shield tunnel:

• 2D or 3D model?
• Interaction between soil and tunnel? Perfect bond (simplified), contact, etc..?
• How to model the tunnel? Linear or nonlinear? Beams or solids?

Dear STKO
Ok, I will continue to explain the details of how to build a shield tunnel

First of all, I want to build a 2D model. The interaction between the liquefied soil (PDMY) and the tunnel is not completely bound. Instead, I plan to use the zerolengthASDIMPLEX element to connect the soil and the structure, and simulate the soil-structure interaction. The tunnel plans to use relatively simple linear and beam elements to simulate



Of course, this may be the first step. The second step is to build a 3D model,

Do you have any video tutorials to guide me to build a model? I will be very grateful

There are couple of webinars in SSI, like #25 or #22
