Through analyzing the testing results from the tests with free vibration column and with dynamic biaxial apparatus for the silts in Shanxi,the dynamic properties of the soils and the variation of pore water during the vibration are studied by the comparison with the variation range of G/G_0-γ and D-γ curves of sand and saturated clay recommended by Seed and Idriss.Testing results show that dynamic shear modulus ratio of silt is higher than that of general saturated sand,but its damping ratio is lower.The relationship between the liquefaction resistance of silt and the cyclic number may be expressed with power function,and its developing regulation of dynamic pore water pressure could be fitted with quadratic parabola function.Based on the local project experience,the results would provide the reference for the design and construction of similar projects.
