Abstract:A comprehensive summary of the various damages on the national and provincial highways in Sichuan Province after the Wenchuan 8.0 earthquake is presented. Typical features of the damages on highway bridges,tunnels,subgrade and pavement have been given. The reasons of earthquake-induced damages have also been outlined from the geological and engineering viewpoints. There is close relation between the destructive degree of bridge and the distance of the earthquake fault. The destructive degree of tunnels is not only related to the distance of the earthquake fault,but also related to tunnel surrounding rock lithology. The soft-hard alternant sediment rock tunnels near the earthquake fault have been seriously destroyed while the granite tunnel has slight damage. The seismic damage of the side slope is closely related to the distance of the earthquake fault,the rock lithology of the side slope and the slope angle. The secondary geological disaster is very serious,which is caused by collapse and landslide of steep slopes formed by granite rock,lime rock and sand rock near earthquake fault.
