Mechanical Response Law and Parameter Influence Analysis of Karst Tunnel Dynamic Excavation

Mechanical Response Law and Parameter Influence Analysis of Karst Tunnel Dynamic Excavation

To ensure the stability of the tunnel structure, this paper simulates the excavation process of shield tunneling in karst areas, and monitors the top of the arch, the bottom of the arch and the waist of the arch within the influence of the cave. It obtains the displacement and stress change laws und...
