Abstract

Abstract

Shear wave in-situ testing is one of the techniques that are commonly useful and effective. The test results can be used for the analysis of soil dynamics. The testing conditions of marine stratum are bad, and in some cases for shear wave velocity prediction is particularly important. In order to study on precise prediction method of shear wave velocity of marine stratum, according to the Jiangsu offshore and intertidal shear wave velocity testing results, the shear wave velocity prediction methods are summarized and evaluated. The statistical relationships between shear wave velocity characteristics and physical-mechanical index of soil are analyzed. Based on the generalized regression neural network (GRNN) method, according to the statistical relationship, the nonlinear mapping relationship between physical-mechanical indexes of the soil and shear wave velocity tested is established. The prediction of shear wave velocity is analyzed and studied. It shows that the good prediction results can be obtained through the method.
