Rainfall-induced slope failure caused severe human and infrastructure damages in mountains area all over the world every year. This paper presents elastic wave velocity affected by soil moisture and shear deformation in slope surface layer using multi-layer shear model tests. The purpose of this study is to investigate wave velocity behaviors with soil moisture and shear deformation, to find out the relationship of the elastic wave velocity with soil moisture and shear deformation and try to apply to early warning system to predict slope failure.
