| 摘 要： | 针对长梁山隧道软弱围岩段的施工难题，采用三维数值模拟于段对施工过程进行了计算分析。根据计算分析的结果，基本掌握了存正台阶、短进尺开挖情况下软弱围岩地段围岩的应力分布特征和变形特性，从而表明对于长梁山隧道的软弱围岩地段采用正台阶、短进尺的施工方案是合理的。

| Abstract: | In light of the construction difficulty during building a long tunnel in soft rock mass,the 3D numerical simulation is used to analyze the construction schedule of the Changliangshan tunnel. According to the numerical simulation results,the characteristics of rock stress distribution and rock deformation becomes explicit in the case of short excavation footage. Consequently,it is reasonable to take above-mentioned construction scheme to excavate Changliangshan tunnel. |
