Comprehensive Treatment Methods of Chaancun Landslide in Dalian City, China

For the past few years, the occurrence of the Chaancum landslide in Dalian city of China has caused great economic loss of about Yuan 46,000,000. The landslide affected the Lvshun highway, Wangjiadian reservoir and the safety of lives and properties of local residents. This has prompted the need to stabilize the slope to avert future disaster associated with landslide and to minimize economic loss and infrastructural damages within the area.
