摘要
In order to discuss whether the CPTU data can be used in soil kinetic parameters computation,the SPSS and OriginPro software are applied to comparatively analyze previous research results and proposed a more suitable formula for calculating the wave velocities(Vpand Vs) of the study area,on the basis of CPTU data and wave velocity testing data of the Hong Kong-Zhuhai-Macao Bridge supplementary investigation project.Depth is considered in the formula that is proposed in the article.The results show that the formula is superior to precursors’ empire formulas,especially when buried depth is greater than 30m of soil mass.The calculations of soil kinetic parameters Ed,Gdand μd are comparatively analyzed.A formula for calculating the soil kinetic parameters in the study area is proposed and the calculation deviation can be tolerated.The results show that calculating soil kinetic parameters with CPTU data are feasible and calculating effects of the method proposed in this article is the best.Meanwhile,it is found that soil depth and correction static point resistance’s negative-index form play an important role in fitting P-wave velocity Vp and shear wave velocity Vs.
