本文用非线性数学规划法建立大坝可靠度的优化解法模型,并编制了相应的计算机程序。该算法可在整个可行解集内探优搜索,得到整体最优解,并可避免JC法有时会出现设计点数值与物理概念矛盾现象。文中用三个计算实例验证该优化方法的有效性。
In this paper, an optimal mathematical model of dam reliability is established by nonlinear mathematical programming and a corresponding computer program is prepared. The algorithm searches the whole set of feasible solutions to get the overall optimal solution and can avoid the sometimes conflicting phenomenon between the design point value and the physical concept in the JC method. Three computational examples are used to verify the effectiveness of the optimization method.
