摘　　要：为了查明谢家店地区水文地质条件,圈定富水地段作为供水水源地以解决淄博市因干旱造成的用水紧缺问题,运用水文地质试验和现场调查分析方法研究了淄博市谢家店地区地质构造特征,深入探讨了地质构造对水文地质边界、水动力条件及含水层富水性的影响,基本掌握了谢家店区域地质构造的控水机制。结果表明:谢家店地区地质构造极其复杂,主要有NE、EW、SN这3组主导方向,大小断裂分布较为集中,主要断层及其破碎带内溶蚀裂隙发育程度高;盆泉—北博山断层和淄河断层是岩溶水运移最主要的导水通道,谢家店断裂(带)则为地下水局部富集场所,河谷下游为邀兔崖阻水地段,使得地下径流受阻于谢家店断层处上升出露成泉;断裂控制的河谷地貌使河谷地下水能轻易接受大气降水和淄河地表水渗漏的补给;地质构造特别是2条主要断层对谢家店区域岩溶地下水的运移、富集起着极其重要的控制作用。研究成果可为谢家店应急水源地建设选址提供科学依据,也可为其他同类地区找水和水源地保护提供科学借鉴意义。In order to ascertain the hydrogeological conditions of Xiejiadian area and delineate the water-rich area as the source of water supply to solve the water shortage caused by drought in Zibo city,the authors used hydrogeological tests and on-site investigation and analysis methods to study the geological structure features of Xiejiadian area in Zibo city,deeply explored the influence of geological structure on hydrogeological boundary,hydrodynamic conditions and water richness of aquifer,and basically mastered the water control mechanism of geological structures in Xiejiadian region.Results showed that the geological structure in the Xiejiadian area is extremely complex,mainly in the dominant directions of NE,EW and SN,with the faults of different sizes intensively distributing,and the dissolution cracks in the main faults frature zone are of high degree of development.The Penquan-Beiboshan fault is the most significant channel for karst water migration and the Xiejiadian fault(zone)provides a place for local enrichment of groundwater,enabling the river valley to easily accept the recharge from atmospheric precipitation and seepage of Zihe river.The lower reaches of the river valley is a water-blocking area called Yaotuya,which makes underground runoff rise at the Xiejiadian fault to form springs,therefore the geological structure,especially the two main faults,plays an extremely important role in controlling the migration and enrichment of karst groundwater in the Xiejiadian area.This study will serve as a scientific basis for the construction and site selection of Xiejiadian’s emergency water source.Furthermore,it is also to provide scientific reference for finding water and protecting water source in other similar areas.
