The paper introduces the theory of rate process and the derivation of the corresponding creep model of creep soils. Three types of clayey soils with different soil qualities are chosen to carry out creep tests. The anisotropic and isotropic structural specimens are prepared respectively and obtained The corresponding creep test results, and finally the theoretical model of the rate of the test results were fitted. The research results show that the creep model based on the theory of rate process can effectively simulate the creep process, trend and deformation of different clay soils, reflecting the essential characteristics of clay soil and making the soil science and soil mechanics compact To combine together
