| Abstract: | By using finite element strength reduction method,the article performs stability analysis on tunnel slope in Jinjishan based on three construction conditions,such as natural slope,tunnel entering without considering cover arch and real tunnel entering.It also studies the impact of cover arch on slope stability,and the stress state of slope structure when ente-ring and leaving the tunnel.This provides reference to design and construction of cover arch. |
