A new method for data processing of cyclic soil test is developed. By using this method, the dependence of cyclic strength on cyclic stress history, number of cycles and static stress state of soil element can be easily obtained. A method for analyzing the bearing capacity is further suggested. On this basis, the effect of cyclic and static coupling of soil element on cyclic bearing capacity is studied.
