This paper introduces the nonstationary nishihara visco-elastoplastic rheological model to be made the constitutive equation of silt clay. Also,there is a method of obtaining parameters of the model,which couples SAA with the finite element analysis by software of ABAQUS and MATLAB. Then,the numerical analysis of settlement is done by the positive direction,that is for the foundation of breakwater after the riprapping. Studies have shown that the numerical method is good to calculate the settlement of silt clay layer in this paper. Finally,the research results can provide a numerical reference for the prediction and control of the settlement of foundation of breakwater.
