Based on the analysis of cyclic triaxial test for the South-Sea sand, a comprehensive normalized model of soil stress-strain relationship is presented herein, which includes effects of not only initial stress states but also loading cycles. Consequently, a pseudo-static procedure to analyse the deformation behavior of foundations is suggested. Example of calculations shows that the suggested procedure is convenient in application.
