Abstract
Because of terrain, geological structure, river down-incising and human activities, the upriver Minjiang Valley in Sichuan Province, Southwest China, constitutes a disaster area prone to frequent landslides. During the roadway rebuilding periods, the Xiaozongqu landslide reactivated on the G213 Roadway in Maoxian District of Sichuan Province. From the September to November in 2002, the landslide sped up, reaching a maximum movement rate of 32 mm/d. The rapid slide seriously threatened the road. To stabilize the landslide and eliminate the damage of landslide to the road, remedying its damage and monitoring further developments are crucial. Based on its kinematic behaviour, remediation was implemented in two phases from November 2002 to October 2003. Systematic monitoring has been carried out since 18 June 2003 to determine kinematic variations of the landslide during the post-remediation period and to assess the effects of remediation and the potential of the landslide for further destructive influences on the roadway.
