Abstract：Based on the data from a typical drilling profile in Hankou and the results of a dynamic triaxial test, the equivalent linear method is used to describe the nonlinear characteristics of soil layers. An one-dimensional wave method is used in soil seismic response. Then, the possibilities of liquefaction for the soil layers within the depth ranging from 10 to 36 m, under different intensities of earthquakes, are analyzed. The results show that: 1) liquefaction is still possible for the sand layers with a depth more than 20 m when the intensity of earthquake is above Ⅶ or Ⅷ degrees; 2) the possibility of soil liquefaction decreases as the depth increases; 3) the spectral characteristics and stationary duration of the inputted ground motion are possible factors that may affect the results of liquefaction. We suggest the method in this paper can provide reference for liquefaction evaluation in deep soil layers.
