Abstract: Through large numbers of geotechnical tests, the correlativity between liquidity index and natural water content, natural void ration, natural density, modulus of compressibility, coefficient of compressibilty, cohesion of silty clay in the subgrade of Su-Tong Bridge Engineering at lower reaches of the Yangtze River was studied, regression equations were given, and the comparison of correlativity curves with other areas in China was also presented. It was found that the correlativity between liquidity index and natural water content, natural void ration, natural density, coefficient of compressibilty was linear, and the correlativity coefficients were over 0.92; the correlativity between liquid index and modulus of compressibility, cohesion is exponential, and the correlativity coefficients were over 0.87; there were better comparability between regression curves of silty clay in Su-Tong Bridge subgrade and regression curves of silty clay in other areas’ subgrade. The following conclusions can be drawn that these regression equations in this paper can provide important reference for silty clay in analogous subgrade.
