The accumulative shear deformation of soft clays under cyclic loads is considered as pseudo-staticcreep.A pseudo-static elasto-plastic cyclic creep model is developed based on the visco-elasto-plastic theory.Theparameters in the model are determined by cyclic triaxial soil tests.A method for analyzing the stability of offshoresoft foundation under wave loads is given by combining the model with pseudo-static creep analysis.An exampleis analyzed by the method.The results show that the horizontal and vertical stability of foundations under waveloads can be analyzed by it and the analytical results are qualitatively consistent with the observed failure modes ofshallow foundations.
