摘要
以实际山岭隧道工程为背景,运用有限差分软件FLAC^(3D)分别研究了主洞和联络通道在不同施工工法以及不同开挖进尺下主洞与联络通道交叉段的沉降及应力演化过程,并通过对隧道交叉段的稳定性分析来优化施工方法及参数。
This paper takes the actual montain tunnel as back-ground,. and uses the finite difference software FLAC30 to simu-late settlement and the changinig of stress of infall between mon- tain tunnel and its connected passage - way under different con-ditions ,such as different construction methods, different excava-tion cycle footage of main tunnel and connected passage - way. Finally, this paper optimize construction method and parameters through the security stability analysis.
