江苏阴平、华冲地区第四纪古河道电性特征研究

Electrical property of Quaternary ancient watercourse of Yinping and Huachong area, Jiangsu Province

从电性、电测深曲线类型和地电结构研究入手,利用电测深技术对江苏东北部阴平、华冲地区第四纪古河道进行了推断解译,指出区内第四纪古河道发育在朱墩—桑墟以东地区,埋深25～50m,尤其是50m左右古河道内砂层颗粒粗、层厚且富水。

Based on the research of electrical property,curve type and terrestrial electricity structure in Yinping and Huachong area in northeast of Jiangsu Province, Quaternary ancient watercourse has been interpreted by using electrical sounding. The results show that Quaternary ancient watercourse only distributes to the east of Zhudun-Sangxu fault. From 25 to 50m depths, especially 50m, sand layer has the characteristics of coarse grain, thick layer and abundant water.
