摘要
随着张北县坝上地区经济发展和人口增长,对地下水的需求剧增,导致地下水位急剧下降,面临水资源匮乏的困境。查明张北县坝上地区的水文地质条件,弄清该地区地下水的赋存规律,是一个亟待解决的问题。利用CSAMT法和高密度电法查明了张北县西大淖村的地层结构,断层以及含水层的分布,精准确定了水文地质钻孔位置,出水量达130 m^3/h,解决了当地水资源匮乏的问题。CSAMT法和高密度电法在勘查玄武岩孔洞水过程中取得了较好的应用效果,为进一步提高张北县的水资源利用率提供重要依据。
With the economic development and population growth in Bashang area of Zhangbei County,the demand for groundwater is increasing sharply,which leads to the rapid decline of groundwater level and the plight of water shortage.It is an urgent problem to find out the hydrogeological conditions of the Bashang area in Zhangbei County and to find out the occurrence law of groundwater in this area.By application of CSAMT method and high density electrical method,the stratigraphic structure,faults and aquifer distribution of xidanao village in Zhangbei County are found out,and the hydrogeological borehole location is determined in detail.The water yield reaches 130 m^3/h,which solves the problem of local water shortage.CSAMT method and high density resistivity method have achieved good results in the exploration of basalt pore water,which provides an important basis for further improving the utilization rate of water resources in Zhangbei County.
