摘　　要：石泉扩机工程电站厂房上部是箱形钢筋混凝土结构,上下游混凝土墙厚为1.45～2.8 m。在设计过程中,借 助大型有限元软件ANSYS对厂房上部结构进行三维应力和位移分析,并按主拉应力对厂房上部结构进行了配筋 计算,降低了工程量。实践证明:这种分析方法是合理的,计算结果也是可靠的。The upper powerhouse for the Shiquan expansion project is of a reinforcement box construction with upstream and downstream walls 1. 45-2. 8 m in thickness. During design, 3D stress and deformation analysis is carried out on the powerhouse superstructure with the aid of finite element software ANSYS, and reinforcement calculation is conducted in terms of the principal tensile stress, resulting in reduced construction quantity. The practice indicates that this analysis method is rational and the calculation results are reliable.
