摘要：

Earthquake can cause severe damage to major projects of Quaternary sedimentary layer, and the vibration liquefaction by shear wave velocity has been widely used due to clear physical significance, high prediction reliability, and good economy. Taking Suzhou as a typical Quaternary sedimentary area, the shear wave velocity data of 40 borehole profiles are fitted and analyzed. The results show that there is an obvious correlation between the shear wave velocity and the buried depth of shallow soil layer. By testing the distribution of buried depth points, the distribution does not meet the normal distribution. The shear wave velocity of different soils varies greatly due to different depth or weathering degree, and the interval difference is between 60 and 190 m/s. Based on liquefaction discrimination methods, the liquefaction of soil layer is distinguished. The results show that the liquefaction probability of Quaternary sedimentary layer is limited. This paper can provide basic data for evaluating seismic impact based on Quaternary sedimentary layer.
