| 摘 要： | 针对悬壁支护结构的可靠度问题，引入了性物进化的遗传算法并对其进行了改进，克服了传统方法容易陷入局部优化值的缺点，将优化方法和可靠性理论有机结合，使可靠性指标的求解问题化为约束条件下目标函数的极小值的优化问题，运用改进的遗传算法对一工程实例中的悬壁支护结构进行了可靠度计算与分析，实例验证了利用遗传算法解决此类问题的有效性。

| Abstract: | The genetic algorithms for simulating the genetic evolutionary process of organisms are introduced and their local optimal value can be overcome. The solution to the reliable index is transferred into the minimum of the target function under the constraint condition by combining reliable theory with optimization. The improved genetic algorithms are applied to calculate reliable index of the cantilever retaining structure in an example that shows that the genetic algorithm has a good application prospect. So a new approach is explored to analyze the reliability of the retaining structure of deep excavation. |
