土体的压缩模量、液限和塑限等物理力学参数是工程地质勘察测试的重要项目,根据广东西部沿海铁路初测的土体物理力学试验,分析了压缩模量、压缩系数、液限、塑限、塑性指数、液性指数等参数与孔隙比、含水率、密度等参数之间的相关关系。通过回归关系式初步估计不易直接测得的指标,节约了测试时间和试验成本。

The physical and mechanical parameters, such as compression modulus, liquid limit, plastic limit and so on, are the most important achievement of engineering geological investigation. Based on the soil physical and mechanical test data of Coastal Railway in West Guangdong, correlation analysis among compression modulus, liquid limit, plastic limit, liquid index, plastic index and pore ratio, moisture content and density, is systematically studied. The results show that there＇s a good correlation between these parameters and the other groups, and the empiric formulas are established. By using these formulas, the parameters which aren＇t got from the test directly, can be easily got.
