北京市通州区龙旺庄隐伏灰岩水源地勘查与评价研究

鉴于平原区深埋岩溶裂隙不勘查比较复杂，通过地面物质，采用瞬变电磁圈定富水带，通过探采结合勘察的方法，在大兴隆起带上通过龙旺庄地区的上叠式小背斜构造位找到了一处中型优质地下水源地；通过历时一年的开采抽水试验，采用相关分析法进行资源计算与评价，在北京市平原区寻找隐优灰岩水是一次理论上和技术上的新突破，对今后平原区深埋基岩找水，勘查与评价都具有借鉴指导意义。

Exploration and evalution of concealed limetone watre sources in Longwangzhuang,Tongzhou district, Beijing

The exploration for the deeply buried karstic fissure groundwater in plain is rather complicated.Based on the surface geophysical prospecting,the transient EM method is used to outline the zone of groundwater enrichment.Through drilling exploration a medium scale groundwater field with mineral spring water is found in the anticline of Daxing die up warping zone in the Longwangzhuang area,Tongzhou.Accroding to the supervisory results of the one year exploration pumping text,the method of correlation analysis is adopted for the exploration and evaluation.It is a breakthrough in theory and technology of searching for concealed limestone in Beijing plain area and provides an experience in searching for deeply buried bedrock water,its exploration and assessment.
