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．
Combined with the design of the Yellow River (river) aqueduct structure in the midline of the South-to-North Water Diversion Project, the optimal design and finite element analysis of the structural steel truss cable stayed aqueducts are carried out. First of all, the structural layout and component cross-section design of the cable-stayed bridge are carried out. Then, using the Super Sap program for its finite element analysis. Based on the checking of the strength and stiffness of each load-bearing component, the optimal scheme of crossing the Huang-aqueduct structure is given through comprehensive comparison of various design schemes.
