发布时间：2019-01-27 21:03
【摘要】：复杂工程地质条件的拱坝常设置重力墩结构,针对拱坝及其重力墩的体型对整体工程安全性和经济性的影响,以坝体-重力墩混凝土方量为目标函数,将《混凝土拱坝设计规范》要求的限制倒悬度、主应力、中心角等作为约束条件,基于ANSYS有限元分析软件的计算模块和优化设计模块进行二次开发,并采用复合形法作为拱坝优化设计的基本算法对拱坝进行优化。结果表明,拱坝体型优化后混凝土体积比初拟体型体积减小12.00%,具有一定的工程实际意义。
[Abstract]:Gravity piers are often set up in arch dams with complex engineering geological conditions. In view of the effect of the shape of arch dams and their gravity piers on the safety and economy of the whole project, the concrete square of the dam body and gravity pier is taken as the objective function. Taking the restricted inverted suspension, principal stress and center angle required by the Code for Design of concrete Arch dams as constraint conditions, the calculation module and optimization design module of ANSYS finite element analysis software are used for secondary development. The composite method is used as the basic algorithm for the optimization design of arch dam. The results show that the volume of concrete after arch dam shape optimization is 12.00 less than that of initial shape, which is of practical significance in engineering.
