Analyze the Cause of Highway Landslide Constructed over the Sandy Area Affected by Underground Water and Treatment Design Solution

Abstract

During construction time, erosion phenomenon occurred in areas from the cross section Km30+100 to the cross section Km 30+320 of the highway project. Affected area caused by erosion is about 200m in length, 8m in depth and 30m in width. The aims of this article are to analyze the cause of highway landslide constructed over the sandy area affected by underground water, to describe proposed design solution for treatment.
