摘要:
 降雨和库水位上升是滑坡失稳的重要因素之一，为探究滑坡变形过程和失稳条件，选取千将坪滑坡为实体对象，制作相似比为1：190的物理模型，在降雨和库水位耦合作用下，通过不同模型倾角角度并辅以监测手段进行试验研究。试验结果表明：滑面倾角越大，在同样诱发因素下越容易失稳；在降雨和库水位耦合作用下，位移基本存在于滑坡前缘，滑坡后缘波动较弱，表现出牵引式滑坡特征；滑坡土压力与位移变化存在一定的对应关系，土压力随着滑坡的缓慢变形逐渐增加，滑坡破坏前瞬间土压力急剧增大达到峰值，破坏失稳时土压力急剧减小，呈现出应力重分布现象。
Abstract:
 In order to study the deformation process and instability conditions of the landslide, the Qianjiangping landslide was selected as the entity object. The physical model with the similarity ratio of 1:190 was made. Under the coupling effect of rainfall and reservoir water level, the experimental study was carried out by means of different model obliquities and subsidiary monitoring. The results show that the larger the obliquity of the sliding surface, the more likely it is to lose stability under the same inducing factors; the displacement basically exists in the front of the landslide, and the fluctuation of the back edge of the landslide is weaker under the coupling effect of rainfall and reservoir water level, which shows the characteristics of traction landslide. There is a certain relationship between the earth pressure and the displacement of the landslide. The earth pressure increases gradually with the slow deformation of the landslide. The earth pressure increases sharply before the landslide is destroyed and reaches the peak, and the earth pressure decreases sharply when the landslide is destroyed. There is a redistribution of stress.
