It also may cause the change of gravitational geomorphological process system, giving rise to soilslip, landslide, fall and so on.
还可能导致重力地貌过程系统的变化，造成土滑、滑坡和崩塌等灾害；
2
Aim To analyze landslip characteristic and its genesis of expansive soil, discuss the slip model and forming mechanism.
目的分析膨胀土滑坡特征及成因，探讨膨胀土滑坡的滑动模式及滑坡发生的机理。

Research results:Residual strength of slipsoil has linear regression with peak strength; plastic index can be better used to estimate residual strength.
