This app is just for Educational purposes developed during my Master Course in Tunnel Engineering at Politecnico di Milano, Italy, May 2019. 

It is a new approach of closed analytical solution to evaluate radial displacements for deep tunnels in cohesive soils, considering face reinforcement and time influence.

It includes three calculation tabs, as per below:

1) unreinforced tunnel front response (undrained)
2) time influence on unreinforced tunnel front response
3) reinforced tunnel front response (undrained)

I might work on some improvements over time but no immediate action is expected at this moment.

Suggestions are very welcome, drop me an email :)
