摘要
结合天荒坪抽水蓄能电站的工程实际，利用三维线性及非线性有限元法研究了大型地下钢筋混凝土岔管的工作性态，分析了在内水压力及外水压力等不同荷载作用下，岔管衬砌的工作特性和围岩的应力分布规律．所得结论为大型地下钢筋混凝土岔管的设计提供了参考．
The working behaviour of the large underground reinforced concrete bifurcation is studied in the light of specific condition of Tianhuangpin pump and power storage station with 3D linear and nonlinear FEM.The working properties in the lining of the bifurcation and the stresses in the surrounding rock under internal and external water pressure are analyzed.The result of the present study provides a reference for designing practice of a underground reinforced concrete bifurcation with large HD value.
