| 摘 要： | 大型土石混合体滑坡是一类受工程地质条件、降水或地震等多种因素影响的滑坡类型，研究其滑坡成因及治理方法对防灾减灾、保障人民生命财产安全具有重要意义。本文以舟曲县江顶崖滑坡为例，通过历史资料调研和现场地质勘察、数值模拟等手段，对该滑坡的成因和稳定性进行详细分析，并提出相应的综合治理措施。结果表明:该滑坡的地形地貌、松散的岩土体是引发滑坡的内在因素，而连续降雨以及江水对滑坡前缘冲刷是滑坡失稳的外在因素。在对滑坡成因分析的基础上，通过改进抗滑桩护壁结构、率先应用装配式框架支护，结合坡面裂缝整治工程等综合治理措施有效地控制住了该滑坡的变形。该滑坡的综合治理措施可为类似的高大边坡工程以及大型土石混合体滑坡治理提供参考。

| Abstract: | The large-scale soil-rock mixture landslide is a kind of landslide type influenced by many factors such as engineering geological conditions, precipitation and earthquake, it is of great significance to study the causes of landslides and control methods for disaster prevention and mitigation, and for safeguarding the safety of people's lives and property. Based on Jiangdingya Landslide in Zhouqu, the causes and stability of the landslide are analyzed in details by means of historical data investigation, field geological investigation and numerical simulation, the corresponding comprehensive treatment measures are put forward as well. The results show that the topography, loose soil-rock are the internal factors that cause the landslide, while the continuous rainfall and the river erosion on the front edge of the landslide are the external factors that decrease the landslide stability. Based on the analysis of the landslide causes, the deformation of the landslide is effectively controlled by improving the structure of anti-slide pile wall, taking the lead in the application of prefabricated frame support, combined with the slope crack treatment project and other comprehensive treatment measures.The comprehensive treatment measures of the landslide can provide reference for similar high slope engineering and large-scale soil-rock mixture landslide treatment. |
