A STUDY ON DYNAMIC STRENGTH AND DYNAMIC STRESS-STRAIN RELATION OF SILT SOIL UNDER TRAFFIC LOADING

Through lab tests by using the typical triaxical test machine-C.K.C, the thesis studies the dynamic strength and stress-strain relation of silt soil under subway traffic loading. And the research shows that the dynamic strength fall as the cycle of the dynamic loading increases, and the stress-strain relation. In addition, the research educes the rules of the dynamic elasticity modulus and dynamic shear strain of the silt soil. The result is beneficial to the design of the subway.
