Abstract Research purposes: The secondary hazards of the slope happen continuously after the Wenchuan earthquake and they cause big losses. In order to provide theoretical guidance for prevention and reduction of the earthquake disaster，the study was done on the slope disease type，the slope characteristics and the distribution and scale of the slope disease based on the investigation of the slope disease along the Wenchuan - Yingxiu section of the Dujiangyang - Wenchuan Highway，the Chengdu - Guangyuan section of the Baoji - Chengdu Railway and the Chengdu – Kunming Railway.
Research conclusions :(1) The 97 slope diseases of six categories were found in the investigated area. Among these diseases，the slide was the serious disease，followed by the landslide and the collapse while there was a little dehris and seldom scattered. The rockfall was common， but its scale was small. (2) The medium loose and broken slope at the high gratitude was generally the potential disease- prone slope. (3) With earthquake effect，the damage degree of slope gradually weakened from the epicenter to the perimeter，it meaned the epicenter was the heavy disaster area，and the slope disease damage gradually decreased with increase of the distance to epicenter. (4 ) The research results can be used in preventing secondary slope disaster in earthquake disaster areas.
