摘要
最危险滑动面的确定是边坡稳定性分析中一个至关重要的问题。利用模拟退火算法,结合简化Bishop法,进行边坡最危险滑动面的搜索。在分析模拟退火法中存在的不足及其根由的基础上,对算法进行了改进。通过计算机编程技术实现了改进的模拟退火算法。计算结果与典型算例对比证明:改进后的模拟退火算法能够有效避免局部最优解,方法具有实用性。
The determination of the critical failure surface is very important in slope stability analysis. The simulation-annealing algorithm, combined with simplified Bishop's method, is used to search for the critical surface of a slope. The algorithm is improved based on analyzing the reasons of the defects of it and is implemented by means of computer programming. Through comparing calculation with typical examples, it shows that the question of local minimization can be avoided effectively using the improved algorithm, so the method has practicability.
