| Abstract: | The tangential modulus is a very important mechanical parameter for the incremental constitutive model, so the research on its law has great significance. The initial elastic modulus has been studied at first. The relations among the initial tangential modulus, the confining pressure, over-consolidation ratio and the initial void ratio are deduced. The triaxial compression test of clay taken from a certain area in Hangzhou is used as verification. |

| Keywords: | initial tangential modulus confining pressure over-consolidation ratio initial void ratio |
