Under the action of earthquake, the slope will be damaged to varying degrees and the stability will be decreased. The stability of these slopes will be further reduced under the action of succedent rainfall and strong aftershocks, which will evolve into landslides. In addition, the damaged slope, even without the influence of external factors, may slip in a period of time after the earthquake, called progressive landslide or delayed landslide. The losses and casualties caused by the above landslides are often more serious than the coseismic landslides. This paper summarized the research results of post-earthquake stability of soil slopes at domestic and abroad. From the aspects of the damage characteristics, the evolve process of instability and the stability evaluation methods of soil slope, three types of landslides which are progressive landslide, post-rainfall and strong aftershocks induced landslide are analysed. The problems existing in the research and the direction of future research are also been discussed, which can provide some reference for related research work.
