On the Causes and Remediation Measures of an Ancient Landslide Hazard
An ancient landslide forepart was excavated due to the highway construction,disturbance and failure to adopt effective reinforcement measures resulted in landslide revival.In addition,the excavation of the dumping ground on the bottom-right of the landslide made the counterpressure of the leading edge invalid,which further aggravated the landslide deformation.According to the site investigation,geological survey,deep displacement monitoring achievements,sliding surface was comfirmed.Furthemore,stability analysis was carried out to determine sliding force,then two rows of prestressed anchor anti-slip piles on the middle and front part of the landslide were set,supplemented by drainage works for comprehensively treated the landslide.Construction period and post-construction monitoring shows that the deep deformation displacement of the landslide tends to converge,which poved the landslide treatment was successful.
