Abstract

Abstract: The process of the construction of the transitional joint arch tunnel of Ziyin Tunnel in Zunyi was simulated by ANSYS FEM program. The stress states of sUITounding rock , ground settlement and the change of intemal forces of tunnel support structure during each period of construction were analyzed by the analysis of 3 excavation conditions. Through the comparative analysis and the monitoring and measurement data in the field construction , it is revealed that different excavation sequences have different effects on the tunnel stlucture in biased state.

Key words: tunnelling engineering, large span, bias arch tunnel, FEM, excavation conditions

摘要： 以遵义市子尹隧道为背景，采用ANSYS有限元分析程序对该工程采用的施工工况进行了二维有限元分析。通过对3种开挖工况的分析，获得了大跨偏压软弱围岩双连拱隧道在不同开挖工况时各阶段围岩的应力状态、地表沉降以及隧道支护结构的内力变化情况。通过对比分析，并结合现场施工监控量测资料，得到隧道处于偏压状态时，不同的开挖顺序对隧道结构产生不同的影响。
