【摘要】 对某公路滑坡的变形特征、成因机制及稳定性进行了详细研究,并提出了相应的防治措施。研究表明:此滑坡为推移式滑坡,坡体的地形及物质组成是滑坡发生的地质基础,大量的降雨是滑坡发生的主要诱发因素;滑坡在自然状态下是稳定的,而在暴雨和地震工况下不稳定;此滑坡防治应以加强排水措施为主,并在前缘修筑挡墙,同时加强监测。查明滑坡的变形特征及成因机制是滑坡灾害评价和防治的基础,研究思路及其成果可供类似滑坡稳定性分析及灾害防治参考。更多还原

【Abstract】 The landslides are most primary geo-hazards of a mountainous area in China. In this paper, the deformation characteristics, formation mechanism and stability of a landslide of a highway are researched in detail, and measures of prevention and cure are put forward. The researches show: the landslide belongs to thrust load caused landslide,the landform and material buildup is geological conditions of the landslide, and abundant rainfall is primary induction factor of the landslide; the landslide is stable under nature conditions, but not stable under rainstorm or earthquake conditions; the measures of prevention and cure of the landslide give priority to drainages, and retaining wall on foreland of the landslide is built, and monitoring measures are enhanced. It is base of landslide hazards appraisement and prevention that deformation characteristics and formation mechanism of landslide are found out, the research ideas and findings can be referred when the stability and preventions of similar landslide are investigated.更多还原
