摘要
分析了贵州省印江县北部杉树乡孟郊滑坡群的形成原因,主要受到地形条件、季节性冲沟的冲刷、后期人类工程活动以及大气降水、生活污水的影响。通过极限平衡法,评估了滑坡区两个主要滑坡HP1和HP2的稳定性系数和剩余下滑推力。分析表明,HP1和HP2滑坡体均处于欠稳定的状态,为避免发生地质灾害,建议尽早进行处理。根据滑坡区水文地质情况以及滑坡体的基本特征,建议采取"抗滑桩、抗滑桩+锚杆框架梁"的治理措施。
In this paper,we analyzed the formation mechanism of Mengjiao Landslide Group in the north of Yinjiang county,Guizhou province. The formation of the landslide group was mainly influenced by topography,seasonal gully erosion,human engineering activities,rainfalls and urban sewage. By using limit equilibrium method,we evaluated the safety factor and the residual sliding force of the two main landslides（ HP1 and HP2） in the landslide area. Analytical results indicated that landslides HP1 and HP2 were both in an unstable state. In order to avoid the occurrence of geological hazards,it is recommended to deal with the landslides as early as possible. According to the hydrogeological conditions of the landslide area and the basic characteristics of the landslides,the use of anti-slide piles and anchor frame beams was recommended.
