    Abstract
  • The geological hazards induced by the Wenchuan MS8.0 earthquake along the Dujiangyan-Wenchuan Highway are especially severe and have seriously affected the safe riding along the highway and the reconstructions. In order to prevent and reduce disasters effectively, main geo-hazard type, slope failure modes and its formation mechanism, and the tempo-spitial distribution in the area have been studied on the basis of the field investigations and statistic analysis of available data. The main damage types include debris flow to collapse, cataclastic rocks to collapse, and shatter-subduction type mudslides, oscillation high-speed sliding debris flows along the slope area. Born transformation induced by such disasters have intensive, systematic and subsection characteristic. Thegeologic hazards have many types and are notably divided into sectors; the high and steep rock deposits of complex origin become the main materials of geological hazards; intense earthquake effect and coupling of endogenic and exogenic forces are important factors for formation and occurrence of geological hazards in the area.
