中文摘要：

通过对形成于1964年～1976年位于黄河口潮坪区粉土层样品电阻率、井中电阻率和电阻率剖面的测试，分析了土的含水率、孔隙比、饱和度、孔隙水的电阻率、颗粒成分等因素对其导电性的影响。分析结果表明：影响该地区饱和粉土导电性的主要因素为土的孔隙率。随着孔隙率的增大，其含水率升高，电阻率降低，土的电阻率和相应孔隙率的关系可用拟合公式表达。基于此，利用电阻率法成功实现了不同深度粉土沉积层微结构的变化、波浪作用导致密实度不同的粉土层空间分布状况的原位测试。

英文摘要：

By sample resistivity testing, resistivity logging and resistivity section measuring for the silty soil layers which has been formed from 1964 to 1976 year in Yellow River estuarine area via Daokou area of Dongying City in China＇s Shandong Province, the relationships between water content, porosity, water saturation, resistivity, of pore water, mineral characteristics and electrical resistivity for silty soil ar＇e discussed. Research results show porosity is the main factor to control the resistivity for silty soil in Yellow River estuarine area. The resistivity for silty soil would decrease as the porosity and water content increasing; the relation formula between the resistivity and porosity also is given. Based on these results, the micro-structure of silty soils and space distributing of silty soil layers also have been mapped with resistivity logging and resistivity section measuring data successfully.
