摘　　要：文章基于大型水利工程引江济淮工程实际,通过对引江济淮工程江淮沟通段的膨胀土土工试验数据进行整理,分析研究不同膨胀等级膨胀土相关物理性指标及物理力学性指标之间的关联性,并结合现场施工地质调查的土体特征,总结不同膨胀等级膨胀土地质特征差异性,可以为更好地了解该区域内的膨胀土特性提供参考。Based on the actual situation of large water conservancy project Yangtze-to-Huaihe River water diversion project,this paper collates the soil test data of expansive soil in Jianghuai communication section of Yangtze-to-Huaihe River water diversion project,analyzes and studies the correlation between the relevant physical and physical mechanical indexes of expansive soil of different expansive levels,and combines the soil characteristics of soil of different expansive levels with the soil characteristics of site construction geological survey,and summarizes the differences in the characteristics of expansive land of different expansive levels.It can provide reference for better understanding of expansive soil characteristics in this area.
