| 摘 要： | 以沪－蓉－西庙垭分岔隧道为工程背景，采用三维快速拉格朗日差分法(FLAC3D)对其浅埋大跨段施工开挖力学响应进行了数值模拟，分析了开挖后围岩的应力场和位移场特征，并结合现场围岩变形和支护结构性态的现场监测，研究了典型地质代表断面的施工力学状态，获得一些有益的结论，对实际工程进行直接指导并为同类工程提供参考。

| Abstract: | The diverging tunnel is a new promising tunnel used in communication construction in West China, Aimed at the problems involved in excavation and research of the large-span and shallow part of Miaoya diverging tunnel in Hu-Rong Expressway, excavation mechanics simulation with FLAC3D is introduced and site monitoring is proceeded at Miaoya diverging tunnel. Based on the results, the excavation mechanics analysis and site monitoring of wall rock deformation and the mechanical character of supporting system are presented; some conclusion is drawn by the analysis of classical geology part of this tunnel. The research will devote to the following studies. |
