摘　　要：结合蒲石河抽水蓄能电站地下引水高压钢筋混凝土岔管实例,利用弹簧简化模型,应用三维有限元非线性计算方法,分析研究了地下钢筋混凝土岔管在充水运行与放空检修工况下,衬砌、钢筋的应力与变形。通过分析计算结果得出衬砌厚度的合理取值,并对衬砌的配筋及最大裂缝宽度进行探讨。Taking reinforced concrete breeches under high pressure in Pushihe pumped storage power station as the example the paper analyses the stress and the deformation of lining and reinforcing bar with three-dimensional non-linear finite element method and simplified spring model under the condition of charging and emptying reinforced concrete breeches pipe,obtains the radonal value of lining thickness and discusses the reinforcement of lining and the width of maximumfissure.
