Abstract Abstract : Research purposes : The subsidence，deformation and cracking of subgrade which were on the left side of a station occurred in DK 51 + 800 ?DK 51 + 880，and it became the landslide disease， endangering the traffic safety. Based on analyzing the causes of the landslide disease in detail， the practice proved that the subgrade was safe and stable by the way of the combination of emergency measures and permanent treatment. Through treatment and summary of a landslide disease at expansive soil embankment，it could be used for reference in the similar project. Research conclusions :( 1) The micro composite piles could be firstly adopted in the emergency rescue project of the sloping subgrade. (2) More attention of waterproof and drainage engineering design shoud be payed to the expansive soil subgrade embankment. ( 3 ) The stability analysis shoud be more for t!ie embankment situated on the slope expansive soil foundation. (4) Overall planning should be considered when determining the reinforcement scheme and the emergency rescue project need to the combination of temporary and permanent engineering when condition permitted. (5) The research results can provide the reference for the problems that should pay attention to and their solutions in the subgrade design under similar geological conditions in the future.
