| 摘 要： | 针对边坡稳定问题的高维非线性、非正态的特点,提出一种基于和声搜索和投影寻踪理论的边坡稳定性评价方法。利用投影寻踪理论将边坡稳定性评价多指标问题转化为单一投影指标问题,采用改进的和声搜索算法优化投影方向,根据最佳投影值实现在低维空间上的边坡稳定性评价。文中建立了基于和声搜索的边坡稳定投影寻踪聚类分析模型,并用作者编制的相关程序实证分析了某水库库区滑坡。实例分析结果表明:基于和声搜索的投影寻踪对于边坡稳定聚类分析是可行的,并且取得了较为理想的效果,为边坡稳定性分析评价提供了一种有效的新方法。

| Abstract: | In view of the nonlinearity and non-norm distribution of slope stability analysis,a new assessment method based on harmony search and projection pursuit is proposed.The method changes the multi-index problem into the problem of single projection index and searches the best projection direction with improved harmony search.The assessment is carried out with the projection value in lowdimensional space.The model of projection pursuit clustering based on harmony search is built and the improved program is used for project application.The analysis result shows that the projection pursuit clustering based on harmony search is feasible with high efficiency,and so provides a new method for slope stability analysis. |
