| 摘 要： | 基于ANSYS软件的优化模块,利用参数化设计语言APDL编制程序,并根据重力坝基本断面的几何特性及约束条件,先拟定一组初始条件对重力坝在各项荷载作用下的应力进行模拟。然后分别使用零阶方法和一阶方法对重力坝断面进行优化设计,使重力坝在满足几何约束条件、应力约束条件和抗滑稳定约束条件的前提下,断面面积最小,实现设计的经济性和可行性,最后将两种优化方法的结果进行对比。

| Abstract: | Based on the optimization module of ANSYS software，a set of initial conditions is studied out at first，and then the stress status of gravity dam under various loading effects is simulated with the parametric design language APDL in accordance with the geometric characteristics and constraint conditions of the basic section of gravity dam. Afterward，the zero-order and first-order methods are respectively applied to the optimization design of the section of gravity dam for making the section area to be minimized under the premise of meeting the constraint conditions of geometry，stress and anti-sliding stability concerned.Finally，the results from both the optimization methods are compared as well. |
