Hello

In bored tunnel problems how the term 'Tunnel Contraction' works? On what basis this value is fixed?

I applied a '2% volume loss of ground' as 'Tunnel Contraction' in my problem. I found increasing the stiffness's and strength parameters of soil mass increases the deformations of tunnel liner more and vice-versa.

What are the terms provided in output-

1) Realised contraction increment (%)

2) Total realised contraction (%)


Thanks and Regards
D
