摘　　要：拓扑优化是目前结构优化领域研究的热点,也是结构优化学科发展的方向,但目前国内对拓扑优化方法在水利工程中的应用研究很少,为此,介绍了拓扑优化方法产生的背景及发展过程,通过对水工建筑物中最常见的混凝土重力坝剖面进行拓扑优化设计,并利用有限元分析软件ANSYS得出拓扑优化结果,表明了用拓扑优化方法进行剖面设计是可行的。Topology optimization is a hot research area in structural optimization, and it is also the development trend of the structural optimization subject. Its theory has been developed well, which has been applied in many fields, such as girder, mechanics, aviation, cosmonautics and microstructure and so on. But there are very few literatures about application to Hydraulic Engineering by using Topology Optimization Method. In this paper, the background of topology optimization is described, and the art state of the Topology Optimization Methods and how to apply this method to the hydraulic structures are discussed. Finally a numerical example is given, in which the section of a gravity dam is designed by using topology optimization method, and its optimization resuh is also obtained by the commercial software ANSYS. It shows that this method is reasonable and effective.
