| 摘 要： | 根据Hasofer-Lind的定义,将复杂的拱坝可靠性指标计算问题转化为数学上的优化问题,针对拱坝功能函数的复杂非线性和隐性的特点,提出基于蚁群算法的拱坝可靠度计算新方法,该方法避免了计算功能函数求导问题,不易陷入局部最优。以沙牌碾压混凝土拱坝的结构可靠度分析为例,得出了该坝坝体及诱导逢可靠性指标的分布规律,与文献2]试验成果吻合。 |

| Abstract: | In accordance with Hasofer-Lind's definition,the reliability calculation problem of arch dams was converted to the problem of optimization.A new versatile optimization algorithm called ant colony optimization was adopted.The algorithm did not need to calculate differential of nonlinear limit functions and do not easy fall into the part best.The method was applied to analyze the reliability of the Shapai RCC arch dam.The reliability Index of the dam and induced joints was calculated with the method.The algorithm for this problem is versatile,robust and efficient. |
| Keywords: | ant colony optimization algorithm arch dam reliability analysis |
