软土物理力学参数的关联性分析

Correlation Analysis of Soft Soil Properties

以江苏某典型软土为研究对象,通过对大量实验数据的统计分析,系统地对软土的天然孔隙比与天然含水量、塑性指数与液限、天然孔隙比与压缩系数、塑性指数与粒径小于0.002 mm的颗粒含量,以及粘聚力和内摩擦角与含水量的关系进行统计分析,建立了软土土性参数的关联公式,为软土地区工程参数的取值提供了依据。

Based on the survey data of a highway,the engineering geology and hydrogeology of soft soil are analyzed. The relationship between natural void ratio and natural water content,plastic index and liquid limit,natural void ratio and compression coefficient,plastic index and the particle size of less than 0.002 mm,cohesion and internal friction angle and water content are systematically analyzed. The correlation formulae of the mechanical and physical parameters of soft soil are established.
