摘要
通过区域地质调查分析、边坡调查、地质灾害调查,并结合沿线岩堆总体发育特征及稳定性调查,初步对该岩堆稳定性做出定性判断。同时,采用国际通用严格极限平衡法、数值计算分析法等多种方法,对多个工况条件下岩堆边坡稳定性进一步验算复核,结合工程建设影响分析确定岩堆不稳定区域及可能工程危害,分类提出处理设计建议。
Through the regional geological investigation and analysis, slope survey and geological hazard survey, as well as combined with the overall development characteristic and stability investigation of rock heap, this paper makes initial qualitative stability evaluation. At the same time, the paper adopts interna- tionally accepted strict limit equilibrium method,numerical computation analysis methods and so on to fur- ther check the stability of rock heap in many working conditions. Combined with the construction impact analysis, the paper determines the rock heap unstable region and possible engineering hazard to recom- mend different proposed processing design.
