The Experimental Study on Dynamic Characteristic of Diversion Dike's Foundation Soil

Through the resonance column test and dynamic triaxial liquefaction test on diversion dike soil of a nuclear power plant,the curves of dynamic shear modulus-dynamic shear strain and damping ratio-dynamic shear strain are gotten,the dynamic deformation characteristics of diversion dike soil are analyzed,the exponentiation function between liquefaction resistance strength and liquefaction shake times of sand soil is studied,and the indexes of liquefaction resistance strength is confirmed.The results provide relevant parameters for evaluating seismic stability and liquefaction analysis of diversion dike.
