| Abstract: | The effects of cyclic dry-wet process on the dynamic stress-strain relationship of the cement silt clay were researched by cyclic triaxial tests.According to elastic modulus Ed、damp λ and dynamic plastic strain εP,a model of the dynamic stress-strain relationship of cement-soil was created. |
