河北省顺平县太行山山前平原区浅层地下水及界河冲积扇电性特征研究

Research on Characteristics of Shallow Groundwater and Jiehe Alluvial Fan in Piedmont Plain of Taihang Mountain in Shunping County,Hebei Province

顺平县界河一带地处太行山山前,以往研究程度偏低。本文在系统研究水文、地质和钻孔资料的基础上,采用高密度电阻率法和激电测深的综合物探方法,根据地电响应特征、激电多参数与含水层富水性的相关性,划定了2个地下水亚系统的界线,指示了富水含水层的分布,对本区的城镇规划、地下水资源合理开发具有重要意义。同时,对比研究冲积扇的电性特征及区域资料,厘清了界河冲积扇的形成时代及迁移规律等演化特征,提升了华北古河道中界河区域的研究程度。

Located in the front of Taihang mountain,the Jiehe area of Shunping county has received limited research attention before.In this paper,based on the systematic study of hydrological,geological and borehole data,the high density resistivity method and IP sounding method are used to delimit the boundary of two groundwater subsystems and indicate the distribution of water-rich aquifers based on the correlation between geoelectric response characteristics,IP multiple parameters and water-rich aquifers.It is of great significance to the urban planning and rational development of groundwater resources.At the same time,the electrical characteristics and regional data of alluvial fans are compared to clarify the evolution characteristics of boundary river alluvial fans,such as the formation age and migration regularity are clarified,and the research level of Jiehe area in paleo-channel of North China is improved.
