摘要
文章采用有限元强度折减法,对金鸡山特大断面连拱隧道的洞口边坡按自然边坡、不考虑套拱的进洞过程、实际进洞过程三种工况进行稳定性分析,研究了套拱对边坡稳定性的影响以及进出洞施工过程中边坡结构的受力状态,为套拱的设计与施工提供参考。
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.
