Abstract

Abstract

Based on the Yamamoto's soil model by considering the Coulomb friction effects,the wave-induced seabed instability has been investigated.An analytical solution is derived for soil response of a finite depth seabed under surface water wave.The effects of wave parameters and soil characteristics on the seabed instability are addressed for three types of soil.Finally,the roles of Coulomb friction stability are then analyzed as well.
- seabed instability,
- shear failure,
- liquefaction
