Abstract: This paper presents an optimization model for reliability degree of large dam using Box’s complex method, and a computer program is also given. The suggested method is able to. Search for the minimal design point within whole allowable zone, and not to make the magnitude of design point contradict physical concept by JC method. Finally three case histories are given to verify the validation of suggested method.?

摘要： 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J C法有时会出现设计点数位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。
