摘要
本文对殷家岩隧道施工过程进行了二维弹塑性有限元分析,得到了联拱隧道在分步开挖时地表沉降、拱顶位移及支护结构的应力变化情况,并得到了几点有意义的结论,为宜长高速殷家岩隧道所采用施工方法及与监测监控测点埋设提供了科学依据和施工指导。
In this paper,the construction process of Yinjiayan Tunnel on Yichang-Changyang Expressway has been simulated based on 2D elasto-plastic structural analysis of FEM program. The ground settlement, arch crown displacement, and the stress state of tunnel's support structure are obtained during each period of construction, and a few meaningful conclusions are presented. This analysis provides the scientific bases and technical guidance for the construction of Yinjiayan Tunnel on Yi-Chang Expressway.
