摘　　要：以ANSYS软件为平台运用现代岩体力学模型即围岩-结构共同作用模型对西沟水电站引水隧洞围岩与衬砌之间的作用进行了有限元仿真分析,通过计算结果得出结论隧洞上拱和下拱的交接处,此处最容易遭到破坏,建议将锚杆预留端头与混凝土衬砌中的钢筋焊接或绑扎在一起,必要时增加一些短插筋,同时对围岩进行固结灌浆。并通过此工程实例计算结果可以得出结论,原则上任何情况下的隧洞都可以用此法求出围岩与支护结构的应力和位移状态。The adjacent formation structure combined action model has carried out the finite element simulation analysis by using the ANSYS software as the platform utilization modern rock mechanical model between the west ditch hydroelectric power station derivation tunnel adjacent formation and the lining work function.The interface point is obtained through the computation results.It is very easy to be destructed,suggested or bound in the anchor rod reservation and concrete lining＇s steel bar welding when the same place,necessity increases some,simultaneously carries on the stabilizing grout to the adjacent formation.And the conclusion can be drawn through this project example.This law can be used in any tunnel to extract the adjacent formation and the support and protection structure stress and the displacement condition.
