Analysis of K103 Landslide Hazard and Its Complehensive Treatment Countermeasures on Hang-jin-qu Expressway

Complexly huge landslide is a kind of intractable objiect to treat with on mountainous highway construction.K103 slope is one of typically latent rock landslide on Hang-jin-qu expressway.Its volume is about 1.60×106m3,and its geology condition is quite complicated.Treament schemes against landslide is intractable to be made for its constant flow of traffic on road.Deformation stage of landslide and sliding condition are both made conclusion by analysis of boring holes with GIS and 2D LEM calculation on slope stability.Comprehensive treatment countermeasures has been taken,and its achieved experience should be shared.
