黄河流域长孝岩溶水系统水文地质特征及蓄水模式分析

Analysis on Hydrogeological Characteristics and Water Storage Mode of Changxiao Karst Water System in the Yellow River Basin

摘要:

基于在黄河流域长孝岩溶水系统开展的1∶5万水文地质调查工作，系统总结了该水文地质单元的边界条件、含水岩组分布及富水性空间分布特征，分析了区内地下水补给、径流、排泄条件与地下水动态变化特征，探讨了黄河长孝单元与周边地下水的相互作用。黄河向北侧补给孔隙水，向南侧补给孔隙水及岩溶水，其中对孔隙水侧渗补给带范围至王营村—庞道口—太平庄—姚河门村一带，对岩溶水补给主要发生在望口山村至柳河圈村一带、孝里镇胜利村附近。圈定了以朱砂洞组为含水岩组的双泉镇段店村裂隙岩溶水富水地段、以三山子组马家沟群为含水岩组的归德孝里马集裂隙岩溶水富水地段，分析其富水机理，总结了层间岩溶断层阻水型及单斜断裂型两种基岩蓄水构造模式，可为该区域找水定井提供参考。

Abstract:

Based on hydrogeological survey with the scale of 1∶50000 conducted in Changxiao karst water system in the Yellow River basin, the boundary conditions, distribution of water bearing rock formations, and spatial distribution characteristics of water richness of the hydrogeological unit have been summarized, groundwater recharge, runoff, discharge conditions, and dynamic changes in the area have been analyzed, and the interaction between the Yellow River and surrounding groundwater has been studied. The Yellow River supplies pore water to the north and pore water and karst water to the south. The range of lateral seepage supply zone for pore water is Wangying village PangdaokouTaipingzhuangYaohemen village. The supply of karst water mainly occurs in the area from Wangkoushan village to Liuhequan village and near Shengli village in Xiaoli town. The fractured karst water rich area are Duandian village in Shuangquan town, with Zhushadong formation as the water bearing rock group, and GuideXiaoliMaji fractured karst water rich area with Sanshanzi formation Majiagou group as the water bearing rock group. Water rich mechanism has been analyzed. Two types of bedrock water storage structures have been summarized, they are interlayer karst fault water blocking type and monoclinic fault type. It will provide some references for water exploration and well location in this area.
