%X In order to explore the features of soil dynamics parameters, first  we sorted out 530 groups  of soils dynamic data by collecting data obtained from 353 boreholes in 146 sites  as well as the results of dynamic triaxial test in the urban area of Wuhan. Then, we classify the data into groups according to soil properties and depth distribution of soil layer. Furthermore, we give the statistical mean value of dynamic shear modulus ratio and damping ratio of 6  typical soils. We take silty clay, clay and mucky soil as examples to present  fitted curves of dynamic shear modulus ratio vs. shear strain and damping ratio vs. shear strain. Through comparison  with  code values and   recommended values, we conclude that dynamic shear modulus ratio is limitedly affected by embedded depth, near to recommended value, whereas relationships among damping ratio of urban area in Wuhan, code value and recommended value are undetermined. The research results can be used as reference for evaluation of seismic safety and application in geotechnical seismology engineering.<br/><br/>
