摘要

以土钉支护结构整体稳定性计算的圆弧滑动简单条分法为基础

运用遗传算法对北京某大厦基坑的土钉支护结构最危险滑移面的位置进行了动态搜索与确定

并计算了其稳定系数。结果表明基坑边坡在实施土钉支护后

其最危险滑移面将后移

同时表明遗传算法能够较准确地确定土钉支护结构最危险滑动面及其相应的整体稳定性系数

且可在优化设计中避免陷入局部最小值

证明了该方法的有效性和准确性。

Abstract

Based on the simple arc-slice analysis method for the whole stability of soil-nail braced structure

calculation of integral stability of a building foundation pit with soil-nail braced structure in Beijing has been carried out by using the genetic algorithms. The results show that the most dangerous sliding-plan will move backward after soil-nail treatment and that genetic algorithms c:in determine the most dangerous slide plane and the corresponding coefficient of integral stability accurately and effectively. Besides

it can avoid getting in local minimum in optimal design. Therefore it is proved that this method is credible and accurate.
