摘　　要：以西南地区某拟建高碾压混凝土重力坝为研究对象,基于有限元分析理论、ANSYS数值分析以及改进的MATLAB优化复合形法,对其溢流坝段断面进行了优化设计研究。依据变形、荷载及抗滑稳定性三个约束条件,建立目标函数模型。经有效的优化设计,在满足安全的前提下,断面面积比初步设计减少15.71%,达到了节约工程造价的目的。Based on the finite element analysis method, ANSYS software and improved MATLAB optimization complex method, the overflow section of a proposed high roller compacted concrete gravity dam in southwest China is optimized.An objective function is established considering three constraints of deformation, loads and stability against sliding.With the optimization design, the section area is 15.71% less than the original design on the premise of safety and the project cost is greatly saved.
