摘要

摘要: 碎石土滑坡已经成为工程建设的主要病害之一。本文从碎石土滑坡发育的工程地质条件出发,通过大量文献研究和工程实践,系统地总结和归纳了碎石土滑坡滑体的物理力学性质和渗透性质,滑带土的颗粒成分、化学成分、微观结构、物理力学性质、遇水弱化性质和渗透性质。根据碎石土滑坡发育的工程地质特性,得到碎石土滑坡的工程地质模型、水文地质模型并提出了防治措施,对于工程实践中碎石土滑坡的稳定性分析和防治方案的设计具有重要的指导意义。

Abstract: Landslides in existing soil and rock debris slopes have become one of the major hazards in projects. The physical, hydraulic and mechanical properties of debris landslide are summarized systematically in this paper. They are the physical, mechanical and permeability properties of sliding-body, the particle composition, chemical components, microstructure, physical properties, mechanical properties and weakening properties of sliding-zone soil. The analyses are based on the engineering geological conditions of debris landslide and extensive literature review and engineering practice, According to the engineering geological characteristics of debris landslide, both engineering geological and hydro-geological models were deduced. They provide a reference for the determination boundary conditions of groundwater seepage induced by rainfall, water level fluctuation of reservoir and rivers in sliding-body. Finally, various prevention measures of debris landslide are systematically summarized.
