河水位骤降条件下某滑坡稳定性分析

Stability Analysis of a Landslide Under the Condition of Sudden Drop of River Level

受特大洪水影响某事务中心管理用房后侧边坡出现拉裂变形,滑坡宽约31m,纵向长约165 m,面积约5.1×10^(3) m^(2),滑体平均厚度约5.0 m,体积约2.6×10^(4) m^(3),为浅层中型土质滑坡。通过工程地质调绘和钻探,查明该滑坡体的工程地质和水文地质条件,根据其变形特征,对滑坡的成因、变形特征及稳定性进行分析评价。

Affected by the extraordinary flood,the slope behind the management house of a certain affairs center was cracked and deformed.The width of the landslide is about 31 m,the length is about 165 m,and the area is about 5.1×10^(3) m^(2),the average thickness of sliding body is about 5.0 m,and the volume is about 2.6×10^(4) m^(3),which is a shallow medium-sized soil landslide.Through engineering geological mapping and drilling,the engineering geological and hydrogeological conditions of the landslide are identified.According to its deformation characteristics,the causes,deformation characteristics and stability of the landslide are analyzed and evaluated.
