渐进结构拓扑优化在重力坝中的应用研究

实体重力坝是重力坝坝型的发展趋势.文章以ANSYS10.0为平台,结合APDL语言,在传统的渐进结构优化(ESO)思想的基础上,采用结构的应变能删除准则,对实体重力坝非溢流坝段进行拓扑优化.优化结果表明:结构的应力和抗滑稳定均满足规范要求,且优化结果与工程实际要求较吻合,同时也从数值上验证了此方法对实体重力坝非溢流坝段进行拓扑优化是可行和有效的.

Application of Evolutionary Structural Topology Optimization in Gravity Dam Design

Abstract: The solid gravity dam is the trade of the gravity dam. The paper makes a topology optimization in solid gravity dam using strain energy removal strategy based on the traditional evolutionary structural optimization(ESO) and in terms of ANSYS analysis software platform, as well as APDL language. The calculation results indicate that: The stress and the stability against sliding are fit for the design specification, and the shape of topology structure approaches the one in engineering practical requirements. Which indicates that the proposed method is feasible and effective for the solid gravity dam topology optimization.
