Shear velocity is an important index for evaluating soil dynamic properties of the site.In thispaper,the statistical relation of shear velocity with soil properties is set up by statistical analysis of shearvelocities and relevant soil properties measured in Tianjin and Shanghai.The obtained formula has somereferential value for the evaluation and classification of the site in offshore areas of China. Shear velocity is an important index for evaluating soil dynamic properties of the site.In this paper,the cradle of the shear velocity with soil properties is set up by the force analysis of shear velocity and relevant soil properties measured in Tianjin and Shanghai.The obtained formula has some referential Value for the evaluation and classification of the site in offshore areas of China.
