| 摘 要： | 徐淮地区的徐宿弧形逆冲推覆断裂构造体系，由一系列近南北向背斜向斜构造和逆冲推覆断裂构成。寒武、奥陶系厚层灰岩中岩溶裂隙水为区域内主要储导水岩系，由推覆构造内一系列的南北向背斜、向斜构成集储水构造。受推覆构造格架制约及岩系隔水岩层的阻隔，难以形成较大规模的地下水富集带。通过查找区内新构造破裂构造带，查明了区内地下水分布规律，确定了区域地下水富集带。确定了其展布空间的方向性，原位破裂性，几乎直立性，延展远，具有间隔性，等距性特征。查找出徐淮地区地下水储集富水带，为该地区地下水开发提供了新的途径。

| Abstract: | Xu-Su arcuate thrusting nappe structural system in Xu-Huai region is constituted by a series of nearly North-South anticline and syncline structure and thrusting nappe structure. In thick layer of limestone of Cambrian, Ordovician, karst fissure is the region＇s main storage rocks, a series of north-south anticline, syncline structure in the thrusting nappe structure are made of storage structure Because of the nappe tectonic framework and water-proofing rock stratum, it＇s difficult to form large-scale groundwater enrichment zone. By searching the new construction rupture tectonic zone, the distribution of groundwater and the groundwater enrichment zone are identified in this area. The spatial distribution of its directionality, in situ rupture, almost orthostatic, extension of the groundwater enrichment zone are confirmed, and a new method could be provided for exploiting the area＇s groundwater. |
