Abstract:K28 area of Chengdu—Nanchong highway is locaded in the landslide section,where the rockmass behaves like fragmentation with low strength and more ground surface water. The construction of the roadbed encountered difficulties resulting from the bad condition. The reason of landslide formation is analyzed,and the comprehensive remedy techniques for landslide control are put forward,which include drainage of surface water,anti-slide piles,anti-slide walls,and bio-engineering for improving the slope stability. The landslide is well controlled after reinforcement with these remedy techniques.
