【摘要】Geotechnical properties have strong regional characteristics, so it is of great significance to identify their regional characteristics for local engineering construction. In this paper, taking the soft clay foundation near the Maanshan River as an example, taking the muddy silty clay as the research object, the buried depth of the muddy silty clay in the research area is shallow, and the soil layer is thick. It is of great significance to find out the physical and mechanical indexes of the soft clay foundation in this area for engineering construction. Based on the statistical analysis of the physical and mechanical indexes of the soft clay foundation soil near the Maanshan River, it is found that the muddy silty clay is 14 m thick, and the physical and mechanical indexes change little with the depth of the soil layer. It is also found that there is a good linear correlation between the physical and mechanical indexes of Maanshan bulk materials. The physical and mechanical indexes of mucky silty clay in the foundation soil of Ma’an bulk material site are significantly correlated, among which the physical indexes are well correlated, especially the linear fitting of void ratio, water content, plastic limit, liquid limit and natural gravity, with the correlation coefficient R2 greater than 0.9. There is some variability in mechanical indexes, but the correlation between mechanical indexes and physical indexes is good, especially the correlation between void ratio and compression coefficient, unconfined compressive strength and cohesion.
