滑坡地质灾害稳定性及治理方案研究

为了保障研究区人民生命财产安全，减少滑坡地质灾害，分析了研究区滑坡所处的地质环境，包括地形地貌、地层岩性、坡体结构、地质构造、水文地质条件、工程地质条件等，得到了该滑坡空间分布范围及形态特征、厚度变化、规模大小及滑带发育情况以及滑坡潜在滑动面及数量、潜在滑带土的物理力学强度参数，可作为支挡的构造物地基的岩、土物理力学参数。根据试验选取合理的参数计算滑坡的稳定性，分析论证失稳破坏机理模式、滑坡发展趋势及规模；并对治理工程措施、结构型式、埋置深度和工程施工等提出工程地质方面的要求和建议，采用抗滑桩及排水防治工程措施相结合方案。研究为该滑坡防治工程设计和监测预防措施提供了可靠的地质依据。

Research on stability of landslide geological hazard and its control scheme

In order to ensure the safety of people′s lives and property in the study area and reduce landslide geological disasters,the geological environment of the landslide in the study area is analyzed,including landform,formation lithology,slope structure,geological structure,hydrogeological conditions,engineering geological conditions,etc.,and the spatial distribution range,morphological characteristics,thickness changes,size and development of the landslide zone,as well as the potential sliding surface and quantity of the landslide are obtained.The physical and mechanical strength parameters of the potential sliding zone soil can be used as the rock and soil physical and mechanical parameters of the retaining structure foundation.According to the test,reasonable parameters to calculate the stability of the landslide is selected,the instability failure mechanism mode,landslide development trend and scale are analyzed and demonstrated.The requirements and suggestions on engineering geology are put forward for the treatment engineering measures,structural type,buried depth and engineering construction,and the combination scheme of anti slide pile and drainage prevention and control engineering measures is adopted.The study provides a reliable geological basis for the design of landslide control engineering and monitoring preventive measures.
