深圳港滨海软土变形指标关联度分析

Relation degree analysis of deformation index of coastal soft soil in Shenzhen harbor evacuating road

以深圳滨海软土的物理力学性质指标为例,应用灰色系统理论对变形指标与物理性质指标进行关联度分析,并探讨了变形指标与物理性质指标之间的线性相关性。研究结果表明:在各项指标中,压缩模量与天然密度的关联度最大;压缩系数与天然含水量关联度最大;而变形指标与物理性质指标之间的线性相关性较差。

This paper takes the physical and mechanical properties of Shenzhen coastal soft clay target as a case study.Utilizing the gray system theory,it was analyzed that the deformation index and physical properties of gray correlation analysis indicators,and discussed the linear correlation between the physical nature and the deformation index.The results of the case study show that,the correlation degree either between the compression modulus and the natural density or between the compression correlation coefficient and the natural water content is the largest;while between the deformation index and physical properties,the linear correlation is smaller.
