斜拉桥式渡槽结构的方案优选和有限元分析

Scheme Optimization and Finite Element Analysis of Cable Stayed Flume Structure

结合南水北调中线工程穿黄（ 河） 渡槽结构的设计，对钢质斜拉桥式大跨度渡槽结构进行了优化设计和有限元分析．首先，对斜拉桥式钢质渡槽进行了结构布置和构件截面设计．然后，采用Ｓｕｐｅｒ Ｓａｐ 程序对其进行了有限元分析．在对各承重构件进行强度和刚度等验算的基础上，通过各设计方案的综合比较，给出了穿黄渡槽结构的优选方案．

In combination with the design of flume structure passing over the Yellow River on the middle route of South North water transfer project,the scheme design and finite element analysis of the long span cable stayed steel flume structure is performed.First, the structural arrangement and member section design of the cable stayed steel flume are discussed.Secondly,the finite element analysis of the flume structure is performed by means of Super Sap program.Finally, on the basis of verification of strength and stiffness of load bearing members,through comprehensive comparison of different design schemes,the optimal schemes of flume structure passing over the Yellow River are put forward.
