摘要
莒县灰岩地层产状较陡,多被断裂切割成若干个SN向窄条带状分布的小块段,岩溶发育具有不均一性,地下水资源缺乏,灰岩地层富水性研究对当地水源供给保障具有重要意义。本文以龙王庙富水块段为例,依据“1∶5万东莞幅、招贤幅区域水文地质调查”的实际调查分析数据,系统地进行富水性研究,从地形地貌、地层岩性、地质构造以及地下水动力条件4个方面分析岩溶地下水富集规律,认为只要在这4个方面具备有利条件,就有较大可能形成相对富水块段。该次在灰岩地区找水的成功经验,对于今后在其他灰岩地区开展找水工程及相关研究具有一定的借鉴意义。
The limestone strata in Juxian county are steep.Most are cut into several small narrow strip blocks with the trend of SN.Karst development is homogeneous and lack of groundwater resources.Study on water abundance of limestone strata is of great significance for local water supply.Taking Longwangmiao waterrich block as an example,according to the actual survey and analysis data of"regional hydrogeological survey in Dongguan and Zhaoxian areas with the scale of 1∶50,000",water abundance has been studied systematically,the law of karst groundwater enrichment have been analyzed from four aspects,they are topographic characteristics,stratum lithology,geological structures and groundwater dynamic conditions.As long as there are favorable conditions in these four aspects,waterrich block can be probably formed.Successful experiences of water exploration in limestone area will provide significant references for water exploration and related research in other limestone strata.
