基于可靠性概念的重力坝优化设计

Optimization Design of Gravity Dam Based on Concept of Reliability

对重力坝的优化提出了基于可靠性的材料力学（Ｊｃ法）优化法和基于可靠性的八结点等参有限元优化法，并与传统定值材力优化法进行比照，编写了ＢＯＸ程序，并通过工程实例的优化设计，用三种方法进行分析比较，得出对优化设计有益的结论．

In this paper, for gravity dam′s optimization, the material mechanics(JC method) optimization based on the concept of reliability and the optimization of the equal parameter finite element method with eight nodes are presented. Compared with traditional optimization method, a corresponding program BOX is programed. Finally, several good results are obtained from a gravity dam′s optimization design with three methods.
