    基于变形破坏模式的滑坡加固方法研究

    REINFORCEMENT METHOD STUDY OF LANDSLIDE BASED ON DIFFERENT DEFORMATION FAILURE MODES

    • 摘要: 在我国滑坡地质灾害繁多,而滑坡的变形破坏很复杂,为了探讨一种较为合理的滑坡加固方法,本文针对3种类型滑坡,分析其变形过程,提出了3种类型滑坡变形破坏模式;基于滑坡的变形破坏模式,结合滑坡的工程地质特征及变形特点,对不同变形破坏类型滑坡分区段开展研究,把牵引式滑坡分为牵引区和被牵引区,推移式滑坡分为加载区和推移区,复合式滑坡分为后缘启动区、中间主滑区、前缘启动区;针对不同类型滑坡,分析滑坡演化过程中不同区的变形先后及相互依存的关系,确定主动变形区和被动变形区,提出了基于变形破坏模式的滑坡加固方法,加固的主要思想为:控制主动变形区、确保被动变形区稳定,即不同区段采用不同的安全系数进行控制,并通过3个典型的滑坡工程实例进行计算分析,论证了此方法在工程实践中具有一定的应用价值。

       

      Abstract: There are a lot of landslide geological disasters in our country, and deformation and failure form of landslide is very complex. In order to explore a more reasonable reinforcement method of landslide, deformation process of three types of landslides is analyzed and deformation failure mode of three types of landslides is put forward. Based on the deformation failure mode and engineering geological characteristics of landslide, and correspondingly retrogressive landslide is divided into traction area(initial slide area) and passive traction area, load-caused landslide is divided into pushed area and loading area, combined landslide is divided into leading edge start area(tractive effect),main slide area and trailing edge start area(loading effect).The deformation sequence and interdependence between different areas during the evolution process of landslide are analyzed, and active deformation area and passive deformation area are defined. In addition, the reinforcement method is put forward for different types of landslides based on the deformation and failure mode of landslide. The main idea of reinforcement method is to control the active deformation area and to ensure the stability of the passive deformation area. That different area uses different safety factor to control. And through the calculation and analysis of three typical examples of landslide, this method which has certain application value in engineering practice is demonstrated.
