摘要
按滑体岩土组成和滑面发育位置 ,黄土地区的滑坡可划分为黄土层内滑坡、黄土接触面滑坡、黄土 泥岩顺层滑坡、黄土 泥岩切层滑坡 4种基本类型。黄土接触面滑坡、黄土 泥岩顺层滑坡的滑速低、滑距短 ,滑体具有稳定性差、复活性强的特点。黄土层内滑坡、黄土 泥岩切层滑坡的滑速高、滑距长 ,滑体稳定性高。但后壁不稳定 ,易再次滑动。这些基本规律对黄土滑坡研究和防治、滑坡灾害预测有一定指导意义和实用价值。
On the basis of how the sliding body is composed of and where sliding plane exists, landslides in loess area can be divided into four basic types.They are homogeneous loess landslide, loess interface landslide, loess-mudstone layer plane landslide and loess-mudstone cutting layer landslide. The characteristics of loess interface landslide and loess-mudstone layer plane landslide are low sliding velocity, short sliding distance and low stability after sliding. And the characteristics of homogeneous loess landslide and loess-mudstone cutting layer landslide are high sliding velocity, long sliding distance and high stability after sliding except its scarp. Basic laws mentioned above have some guiding significance and practical value.
