泰山北翼岩溶含水介质分布及地下水循环规律研究
Study on the distribution of karst water-bearing medium and groundwater circulation pattern in the north flank of Mount Tai
摘要
Abstract
In order to gain a comprehensive understanding of the circulation process of karst spring and geothermal water in Ji'nan on a larger spatial scale,this research paper analyzes the burial conditions and continuity characteristics of carbonate water-bearing media based on their spatial distribution in the north flank of Mount Tai.Furthermore,the study reveals the pattern of regional groundwater circulation through the utilization of mathematical statistics,spatial interpolation,a Piper three-line diagram,a conceptual model,and the"four fields"analysis of hydrodynamic field,hydrochemical field,water temperature field,and water age field.The results show that the spatial distribution of karst water-bearing media in the north flank of Mount Tai is controlled by surface watersheds and deep faults such as Qiguang fault,Yuwangshan fault,and Liaokao fault.There is a gradual increase in burial depth from south to north.Additionally,the hanging wall and footwall have different dislocations due to the influence of secondary faults such as Mashan fault,Dongwu fault,and Wenzu fault.However,there is still a general continuity in their East-West distribution.The regional groundwater circulation process is extremely complex.The Taishan rock group,Cambrian,and Ordovician water-bearing rock groups interact with each other through various means such as surface flow discharge,leakage,structural connectivity,and underground runoff.In certain areas of piedmont,karst water exchanges with Quaternary loose-pore water and ultimately discharges through springs or artificial mining.The regional groundwater flow exhibits a unified"four fields"and demonstrates distinct horizontal and vertical zoning characteristics.The boundary between cold springs and geothermal springs is formed along the Donge fault and its extension line,encompassing Wujiabao,Huashan,Zhangqiu and Cicun.The circulation depth boundaries of shallow,medium,and deep flow are roughly divided at 600 m and 1000 m.Cold springs are predominantly characterized by shallow circulation,supplemented by medium and deep circulation,with low groundwater mineralization,temperature,and age.On the other hand,geothermal water is dominated by medium and deep circulation,supplemented by shallow circulation,with large groundwater mineralization,temperature,and age.The flow of different aquifer media exhibits certain internal correlations,forming a complete karst water system.关键词
