以典型碎石土堆积层滑坡黄莲树滑坡为研究对象,深入分析了降雨诱发滑坡滑动的形成机理,采用地学模拟软件GeoStudio中的SEEP/W模块和SLOPE/W模块建立相应的模型,根据诱发滑坡时的降雨量设置不同降雨工况,将瞬态孔隙水压力分布用于滑坡极限平衡稳定性分析中,从而确定不同工况下的滑坡稳定性系数,从稳定性分析结果可以看出该滑坡对暴雨及大雨响应敏感,降雨强度及降雨量越大稳定性下降越明显。该滑坡的成灾机理及滑动过程为类似滑坡险情出现时的应急处置及防治提供了可靠的借鉴经验。
Taking Huanglianhu landslide of typical rubble accumulation landslide as the research object, the formation mechanism of rainfall-induced landslide sliding is analyzed in depth. The SEEP / W module and SLOPE / W module of geoStudio are used to establish the corresponding models. According to the landslide induced Of rainfall set different rainfall conditions, the transient pore water pressure distribution for the landslide limit equilibrium stability analysis to determine the landslide stability coefficient under different conditions, from the stability analysis results can be seen that the landslide on the heavy rain And heavy rain response is sensitive to the rainfall intensity and rainfall greater decline in the stability of the more obvious. The disaster mechanism and the sliding process of the landslide provide a reliable reference for similar emergency treatment and prevention when landslide danger appears.
