SUMMARY This webinar showed how to use the Finite Element Method (FEM) to simulate the staged construction of a tunnel by a Tunnel Boring Machine (TBM) in soft soil. The tunnel support system has double lining, prefabricated segments and sliding formwork.
The webinar also discussed important issues of excavating tunnels on soft soil, like the effect of regional subsidence. Lastly, it covered why consolidation analysis was done to account for pore pressure reduction through drains.
