摘　　要：通过在汉江遥堤钻孔取样 ,直接进行试样的电导率和土质、含水量、干密度、孔隙比以及颗粒级配等土性参数测试 ,建立堤防材料的电导率与多种土性参数的相关关系 ,目的是为提高物探结果解读准确性提供试验和理论基础。研究结果表明 :电导率与黏粒含量、含水量和孔隙比呈正相关 ,与干密度呈反相关 。The authors established a co relationship between conductivity of dikes and geo technical parameters, such as moisture, dry density, porosity, gradation, soil quality, etc.,based on data analysis of sampled drills at Yaodi dike of the Hanjiang River.The co relationship is a theoretical and experimental foundation for correct analysis of geophysical detection results. The research showed that the conductivity had a direct co relationship with clay content, moisture and porosity and a reverse co relationship with dry density. It seems that the conductivity had no obvious relation with silt content.
