How can I overcome/rectify this void around the tunnel?
Sanaz Karimi
Hello, I modeled a tunnel of 2.5 m in the soil layer. In the calculation result at the lining stage voids are created around the pipe. How can I remove these voids? what is the reason behind this phenomenon? Many thanks for your help.
