| 摘 要： | 采用GeoFBA软件,对沈阳地铁隧道开挖全过程进行数值模拟研究,对围岩、喷射混凝土、模筑混凝土、锚杆的应力和变形特征进行分析.结果表明,沈阳地铁隧道设计当中初拟的结构尺寸（包括初期支护、二次支护）、超前小导管支护、锚杆支护是可以适应围岩状况的,经支护后的沈阳地铁隧道是稳定的.台阶法开挖对于沈阳地铁隧道开挖是适用的.

| Abstract: | By the GeoFBA, numerical simulation study on excavation process of Shenyang metro tunnel was conducteck The stress and deformation of surrounding rock, spray concrete, site-casting concrete, and stress and deformation characteristics of the anchor were analyze＆ The results show that the structure size prepared by the design of the Shenyang metro tunnel （including the initial support and secondary support）, advance timbering, and bolting can be adapted to the situation of the surrounding rock. Shenyang metro tunnel is stable after the support. Benching tunnelling method is applicable to Shenyang metro tunnel excavation. |
