某厂区边坡支护方案及其滑坡地质灾害成因机制分析

Slope support scheme analysis for a plant and the causal mechanism of landslide geological disasters

某酒厂陶坛库北侧山体发生滑坡地质灾害。本文通过调查厂区滑坡的基本特征,结合厂区边坡支护情况,分析该区段边坡发生工程滑坡的成因机制。滑坡区位于酒厂陶坛库北侧第一区段支护边坡,地形地貌及地质条件是影响滑坡的内在因素,降雨、不合理支护方案及工程活动为主要的诱发因素,在连续降雨下边坡支护结构底部浅层薄层状强风化泥岩岩体发生溃屈破坏,导致该边坡区段发生小型中层推移式岩质滑坡。

A landslide geological disaster occurred on the north side of the pottery container warehouse at a winery.This paper investigated the basic characteristics of the landslide in the plant area and analyzed the causal mechanism of the engineering landslide on the slope,considering the site's slope stabilization measures.The landslide area is located on the first section of the supporting slope on the north side of pottery altar container warehouse.The topography and geological conditions are internal factors affecting the landslide.Rainfall,inadequate support scheme,and construction activities are the primary triggering factors.During continuous rainfall,the shallow,thinly-bedded,strongly weathered mudstone rock mass at the base of the slope support structure experienced collapse and failure,leading to small medium-sized translational rockslides landslides in the slope section.
