Abstract The slope diseases caused by earthquake are different from other types of slope diseases in general. They have various mechanism and deformation failure modes and can cause large damages. In order to prevent and control these diseases pointedly, based on investigations of 3 slope diseases along the Wenchuan-Yingxiu Road influenced by the "5·12" Wenchuan Earthquake, the analyses and researches were made and done on the slope diseases types, slope structures and mechanism to summarize the deformation failure modes of slope diseases caused by earthquake.
Research conclusions: (1) The main types of slope diseases include the collapse, landslide, slumping, fault and rockfall. Collapse is the major disease, up to 71% of the total slope diseases. About 80% diseases happens to rock slope. (2) The deformation failure modes of collapse have 8 types like pull cracking and falling. Landslide has 5 types like pull cracking, shearing off and sliding. Slumping has 2 types of shaking loose and slumping. Rock falling has 2 types of throwing and dropping. Disorder falling has 1 type of shaking to crimping. (3)This research result can provide the reference to prevention and control of the slope diseases caused by earthquakes along railways and roads.
