摘要
依据隧道地质条件及膨胀土的物理力学参数指标,采用离散元分析计算软件UDEC(Universal District Element Code),建立了数值计算模型,对围岩的变形过程进行了数值模拟,根据数值模拟结果,提出了相应的施工建议和围岩失稳破坏的治理措施。
Based on index of the tunnel geological conditions and physical and mechanical parameters of expansive soil,discrete element analysis software UDEC（Universal District Element Code）is adopted and a mathematical model is established to simulate deformation process of surrounding rock. Regarding results of numerical simulation,suggestions and corresponding control measures for construction and surrounding rock instability and failure are put forward.
