摘要
我国西北地区黄土分布广泛,受半干旱气候影响,黄土边坡多为非饱和边坡,降雨引发的非饱和黄土滑坡频发。通过分析非饱和黄土的特性,根据降雨入渗特征,建立边坡模型,编制计算机程序,计算边坡稳定系数,分析了雨季较易发生滑坡的原因。
Loess is widely distributed in Northwest China, which is mostly unsaturated slope affected by the semi arid climate , unsaturated loess landslide occurs frequently caused by rainfall.Through the Analysis on the characteristics of unsaturated loess, according to the characteristics of rainfall infiltration,a slope model is established,a computer program is written, the stability coefficient of the slope is calculated, and then The causes of landslide in rainy season are analyzed.
