%X 根据乌东德水电站左岸导流隧洞进水口渐变段的结构形式, 设计了一种大型双曲面衬砌钢衬。利用有限元软 件ANSYS 对设计方案进行了静力学分析, 结果表明初始方案的结构应力偏大, 且重量过大, 有必要对方案进行改 进。基于WORKBENCH 的拓扑优化结果, 提出了一种改进方案, 并对改进方案进行了验证。改进方案与初设设计 方案相比减轻了471 0%的重量, 节约了成本, 且刚度和强度均满足施工要求。可为类似工程提供有效借鉴。  According to the structural fo rm of the tr ansit ion o f t he water int ake area in the left diversion tunnel o f Wudong de hy2 dro power stat ion, a larg e hyperbolic steel liner was designed. The static analy sis of the design scheme w as conducted using the finite element softw are ANSYS. T he r esults show ed that the structural stress of the initial design scheme of mo ld is high and the w eig ht is larg e, so the design scheme needs to be impr oved. According to the to po lo gical optim izat ion results based o n WORKBENCH , an impro ved desig n scheme w as pr oposed and verified, which can decrease t he w eight o f mold by 471 0% com2 pared w ith the o riginal scheme. Meanw hile the cost was saved and the stiffness and strengt h of the mold satisfied the construc2 tion requirement. The research results can pr ov ide r eference fo r the similar engineer ing pro jects.  三峡大学研究生科研创新基金
