摘　　要：利用拓扑优化方法中的均匀化方法,根据拱坝特点,以体积最小为目标,对拱坝的体形优化进行了研究;基于ANSYS有限元分析软件,对拱坝二维水平拱圈的拓扑优化进行了详细分析,得到了较为满意的结果,这表明拓扑优化方法应用于拱坝体形优化设计是可行的.According to the arch dam features, with the object of the minimum volume, the form optimization design of arch dam is studied by homogenization method which is often used in topology optimization. Based on the finite element analysis software of ANSYS, 2-D horizontal ring topology optimization of some arch dams is accomplished. All the results are satisfied, which indicates that the Topology Optimization method is fit for the arch dam optimization design.
