岩质边坡潜在滑块搜索方法及工程应用

Research and application on potential sliding block searching method of rock slope

岩质边坡安全系数的搜索方法一直是工程界的热门话题,本文基于第二类非圆弧滑动面特点,采用模式搜索法及形搜索法分别搜索岩质边坡的潜在滑动面,从搜索效果及搜索原理等方面,对比其搜索结果,总结其适用条件。结合工程实例,比较分析以上两种搜索方法的结果,得出在岩层分布倾角较小时,两者分析结果非常接近,为类似工程提供建议。

Search method of rock slope safety factor is always a hot topic in engineering, based on the characteristics of the second type of non-circle slide surface, the pattern search method and the form search method is adopted to search the potential sliding surface of rock slope. Based on the search results and principle, comparing its results, the applicable conditions are summarized. Combined with engineering example, search results analyzed by the above two methods are compared. The results show that when the distribution of the strata dips angle is small, the analysis results are very close. Suggestions for similar projects are provided.
