摘要

通过大量的土工试验，对长江下游苏（州）—（南）通大桥工程区粉质黏土液性指数与天然含水率、天然孔隙比、天然密度、压缩模量、压缩系数、黏聚力的相关关系进行了研究，给出了它们之间的回归关系式，并与国内其他地区的情况进行了比较，发现液性指数与天然孔隙比、天然含水率、天然密度、压缩系数呈很好的线性相关关系，相关系数达0.92以上。（2）液性指数与压缩模量、黏聚力呈较好的指数相关关系，相关系数达0.87以上。根据国内其他地区的地层资料，得出了液性指数与其他物理力学参数的近似相关关系曲线。比较苏通大桥工程区与其他地区的粉质黏土液性指数及其他物理力学参数的相关关系式，显示它们之间有较好的相似性。结果表明，研究结果对类似场地粉质黏土具有重要的参考价值。

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.
