摘要
龙马水电站非对称月牙肋钢岔管规模较大,是工程设计的关键。围绕岔管体形和钢材厚度优选,以及围岩与钢衬联合受力等课题,采用三维有限元方法对钢岔管应力变形进行了深入研究。计算与实际运行成果表明:岔管设计体形良好、结构安全。
With a large scale and unsyrrmaetrical layout, the design of crescent fib reinforced steel branch pipe is the key of construction of Longma Hydroelectric station. The paper makes a deep study on stress and deformation of the steel branch pipe by using three - dimensional finite element method, focusing on configuration of the branch pipe, optimal selection of steel thickness and joint stress - withstanding of surrounding rock and steel lining. The calculation and practical operation results show that the configuration of the branch pipe is good and its structure is safe in terms of design.
