So the systematically study of loess landslides are emergently needed. Based on detailed investigation and survey of characteristics of environmental geology, engineering geology, hydrometeorology in Tongchuan, the distribution characteristic and the outer, inner factor of loess landslides are studied; and it is concluded that the rainfall and artificial engineering activity are the leading causes of loess landslide among various factors. Through plenty of tests of soil samples, it is researched that the loess"s physical mechanics characteristics, the loess landslide"s formation mechanism and kinematics mechanism.

本文在详细调查和勘察铜川地区的环境地质、工程地质及气象水文特征的基础上，对黄土滑坡的分布特征和滑坡形成的内外因素进行了深入剖析，认为在各种影响因素中，大气降水和人类工程活动是铜川黄土滑坡的最主要的诱发因素；在采集大量的土样并进行试验的基础上，对黄土的物理力学特征和黄土滑坡形成机理、运动学机理进行了研究，推导出了滑坡运动机理中的孔压参数A_D、B_D分别与孔隙比和饱和度的统计关系。
