Would you please introduce some basic papers in field of numerical simulation of tunnels in FEM, which contains the appropriate element type, constitutive model and important points about construction steps?
Dear Mr. Madahi,
the constitutive model you use is dependent of your type of soil, construction method etc.. So we need information about the geology, geotechnical parameters and boundary conditions.
If you are dealing with weak rock I can introduce you many papers on the topic. Just leave a reply here.
Best Regards
I will be appreciated if you can introduce some of them.
all the best
You can apply a technology able to simulate growing concrete structures. The application is the annexed paper is for bridges, but the same can be used to tunnels.
See annexed paper.
Thank you very much Prof. Majorana. Do you have any opinion about the soil-structure interaction which significantly affects the results? Cause I want to simulate construction steps to achieve a precise model.
