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

Through the indoor resonance column and dynamic tri-axial test of liquefaction on diversion dike soil of a nuclear power plant, its got the curves of dynamic shear modulus-dynamic shear strain and damping ratio-dynamic shear strain, analyzed the dynamic deformation characteristics of diversion dike soil, studied the exponentiation function between liquefaction resistance strength and liquefaction shake times of sand soil, confirmed the indexes of liquefaction resistance strength, providing the relevant parameters for evaluating seismic stability and liquefaction analysis of diversion dike, and reference value for the seismic safety evaluation and liquefied evaluation of the dam project site.
