The correlation of indexes of sub-grade quality inspection including porosity(n),foundation coefficient(K30),deformation modulus(Ev2)and dynamic modulus(Evd)is studied in this paper.These data was tested in experimental section of WUGUANG special line for passenger train.The results prove that:the porosity and foundation coefficient K30,deformation modulus Ev2,dynamic modulus is correlative to a certain degree.Porosity can be obtained at laboratory and method is simple and easy.While the other three indexes must be measured in site,it is difficult relatively.Through their relevance of porosity,the foundation coefficient K30,deformation modulus Ev2 and dynamic modulus Evd can be deduced.According to the results mentioned above,the effect of roadbed filling will be evaluated preliminarily.
