摘　　要：在汶川地震及其次生山地灾害的共用作用下,地震灾区的道路损毁非常严重。汶川地震发生后,政府及相关部门立即组织地震灾区道路的抢通以及恢复与重建工作。都汶公路是汶川地震的抗震救灾的"生命线",是汶川地震受损最严重的山区道路之一。以都汶公路为例,介绍都汶公路路基、路面、桥梁、隧道等损毁情况以及恢复与重建。对于影响都汶公路通行的边坡地质灾害,在通过对边坡地质灾害的现场调查后,确定都汶公路首批恢复与重建的42处边坡处治路段及处治措施,并在9处路段通过修建明洞来预防边坡地质灾害。Under the action of earthquake and its induced geo-hazards,the roads in the earthquake areas were dam-aged seriously.The restoration and reconstruction of the roads were launched immediately by the government and relative departments after Wenchuan earthquake.Taken the Du-Wen highway as an example,the damaged condi-tions about subgrade,bridges,tunnels were described in detail,and the restoration and reconstruction of Du-Wen highway were introduced concretely.Through the investigation of geo-hazards on slopes,different control measures were chosen to geo-hazards for the slopes of forty-two sections.Moreover,nine cut-and-cover tunnels were construc-ted in nine sections.
