摘要
本文以祁连山区山水林田湖生态保护修复试点项目为背景,在查明祁连山区某公路滑坡范围、周界及滑动面深度等滑坡要素、滑体和滑动面物理力学性质的基础上,结合地形地貌、地层岩性、强烈新构造运动、水文地质条件及人为因素的影响,分析了滑坡成因、滑坡变形特征、滑坡失稳致灾的可能性。同时,利用剩余推力法对滑坡的稳定性进行了分析计算,对滑坡敏感性因素进行了分析,提出了滑坡处理建议,以减少对坡下公路和过往车辆、人群的生命财产的威胁,促进该地区的经济发展、社会稳定及生态环境稳定。
In this paper,taking the pilot project of ecological protection and restoration of mountains,water,forests,fields and lakes in Qilian Mountains as the background,combinbing the influence of topography and topography,stratigraphic lithology,strong neotectonic movement,hydrogeological conditions and human factors,the causes of landslides,deformation characteristics of landslides and the possibility of landslide instability and disasters were analyzed based on the identification of the landslide range,perimeter and sliding surface depth and other physical and mechanical properties of a highway landslide in the Qilian Mountains.At the same time,the residual thrust method was used to analyze and calculate the stability of the landslide,the sensitivity factors of the landslide were analyzed,and the landslide treatment suggestions were put forward to reduce the threat to the life and property of downhill roads,passing vehicles,and people,and promote economic development,social stability,and ecological environment stability in the area.
