摘要： 对牡丹江市主城区以往土工试验成果进行综合研究，利用数据统计与回归分析方法总结得出了主城区细粒土物理性指标与力学性指标间的一些规律性认识。结果表明，主城区内细粒土的密度（ρ）、含水量（w）和液限（wL）等物理性指标变化在一定范围内，通过参考值范围可大致判断出细粒土的类型与物理性特征；物理性指标与力学性指标具有明显相关性，〖JP2〗压缩模量（ES）及抗剪强度指标均与密度（ρ）呈正相关关系，与含水量（w）呈负相关关系。

Abstract: This paper summaries statistical laboratory test results on fine grained soil samples from the urban Mudanjiang City. The correlations between physical indices and mechanical properties of fine grain soils are statistically analyzed by using regression method. Results show that the physical indices of finegrained soil samples from urban city, such as density (ρ), moisture content (ω) and liquid limit (wL) are within in a predictable range. The value of these physical characteristics of fine-grained soil could be related to the range of soil type and their mechanical properties. There is obvious correlation existed between physical indices and mechanical properties. The compression modulus (ES) and shear strength values are positively correlated with density (ρ), and negatively correlated with moisture content (ω).
