| Abstract: | 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. |
