摘　　要：通过动三轴试验,研究干湿循环过程对水泥改良粉质粘土动应力应变关系的影响,并据试验结果从弹性模量Ed、阻尼比λ、振动塑性应变εp三方面建立了一种描述此种改良土动力特性的应力应变关系模型。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.
