【摘要】 以我国某大型抽水蓄能电站工程为实例,利用大型通用有限元软件ABAQUS对该电站尾水钢筋混凝土岔管洞段围岩及衬砌的变形和应力状况进行三维有限元分析,根据计算结果对衬砌进行了配筋计算,提出了在实际工作中应做好围岩的固结灌浆、衬砌和锚固的建议.更多还原

【Abstract】 In accordance with the practice of a pumped storage station’s underground reinforced concrete bifurcation,the stresses and deformation of the surrounding rock and lining are simulated by 3D FEM ABAQUS which is a general-purpose finite element analysis sofeware.Moreover,the preliminary calculation of the reinforcement for concrete lining is proposed,some suggests are proposed about doing well solidening and grouting of surrounding rock and lining and anchor.更多还原
