In light of the stability of coastal levee on soft foundation

according to the time-dependent properties of soft soil and the coupling properties of seepage field and stress field

creep model of soft soil and analytical model of coupling stress field are established; and the deformation properties are analyzed by taking the coastal levee and its foundation as a whole. The overall stability under the coupling force of dead-weight

wave force and seepage force is analyzed by the shear strength reduction with FEM. Results show that the coastal levee structure under the comprehensive functions of many effects

not only there are more impact on displacement field and stress field of foundation and section

but also the overall stability. The validity of the model and computing technology is proved by compared with the measured data; and the conclusions obtained in this paper have theoretical meaning and practical value.
