摘　　要：应用三维拓扑优化理论,编制了相应的计算程序,并结合高拱坝结构特点,固定拱坝上游面,对高拱坝三维空间结构进行了拓扑优化计算.结果表明,优化所得拱坝体型与常规坝体体型基本一致,强度满足应力要求.The relevant computer program was compiled according to the theories of 3D topology optimization. Based on the characteristics of high arch dams, topology optimization was performed for a 3D spatial structure with a fixed upstream face. The calculated results show that the shape of the high arch dams obtained by the topology optimization agrees with that of conventional dams, and the strength satisfies the stress requirements.
