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 (w_L) 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 (E_S) and shear strength values are positively correlated with density (ρ), and negatively correlated with moisture content (ω).
