山区缓坡堆积体滑坡治理实例分析

Case Analysis of Landslide Treatment on Gentle Slope Accumulation in Mountain Areas

文中以某山区高速公路所在的缓坡堆积体滑坡治理为例,结合地质勘察及倾斜摄影、深部位移监测等手段综合分析滑坡范围、变形特性及滑面位置,再结合室内试验和工程类比,综合分析岩土体的参数,利用不平衡推力法进行稳定性分析及滑坡推力计算,最终通过分期治理,使滑坡得到了有效控制。

Taking the treatment of the gentle slope accumulation landslide of a mountain highway as an example,combined with the traditional geological survey,oblique photography,deep displacement monitoring and other means,the landslide range,deformation characteristics and sliding surface position were comprehensively analyzed.The indoor test and engineering analogy were combined to comprehensively analyze the parameters of rock and soil mass,and the unbalanced thrust method was used to analyze the stability and calculate the landslide thrust.Finally,the landslide has been effectively controlled through staged treatment.
