Effect of Snow Cover on Slope Stability of Embankment during Rainfall and Snowmelt

Abstract

In this study, the effect of snow cover on slope stability was examined to more accurately evaluate the risk of snowmelt hazards. Firstly, laboratory tests were carried out to determine strength characteristics of snow. In addition to laboratory tests, sprinkling model experiments were conducted on a snow-covered embankment model to observe the moisture response and deformation of the embankment. In addition, slope stability analysis using a finite element method was carried out on the snow-covered embankment model. The result confirmed that snow cover could restrict the surface layer of an embankment and slightly improve the slope stability.
