山东省泰安市城区-旧县岩溶水系统位于山东省中部的泰山南麓,为单斜构造式岩溶含水系统,由城区和旧县两个水源地组成,地势总体北高南低,面积约112 km2。含水系统内地层以新生界第四系和古生界寒武、奥陶系为主,此外,在南部和北部分布有较大面积的太古界泰山岩群火成岩。本区在构造单元上属鲁西台背斜的一部分,泰莱断陷盆地之西半部。区内断裂构造发育,主要有 NE向的泰山断裂、徂徕山断裂及结庄断裂,NW向的洪沟断裂、滂河断裂、岱道庵断裂。含水系统包括第四系松散岩类孔隙含水岩组和寒武-奥陶系碳酸盐岩类裂隙岩溶含水岩组,地下水动态受降水及人工开采影响明显。截止2012年底,地下水日均开采量为5.2万 m3,接近系统允许开采量5.79万 m3,处于采补平衡状态。本文在充分利用前人研究资料的基础上,通过对牟汶河修建拦河坝,河水位抬高引起的岩溶水补给条件变化的研究,确定该含水系统尚具有开采潜力,其潜力主要来源于地表水入渗补给。通过研究计算,目前该含水系统还具有约 2万 m3/d 的开采潜力。
山東省泰安市城區-舊縣巖溶水繫統位于山東省中部的泰山南麓,為單斜構造式巖溶含水繫統,由城區和舊縣兩箇水源地組成,地勢總體北高南低,麵積約112 km2。含水繫統內地層以新生界第四繫和古生界寒武、奧陶繫為主,此外,在南部和北部分佈有較大麵積的太古界泰山巖群火成巖。本區在構造單元上屬魯西檯揹斜的一部分,泰萊斷陷盆地之西半部。區內斷裂構造髮育,主要有 NE嚮的泰山斷裂、徂徠山斷裂及結莊斷裂,NW嚮的洪溝斷裂、滂河斷裂、岱道菴斷裂。含水繫統包括第四繫鬆散巖類孔隙含水巖組和寒武-奧陶繫碳痠鹽巖類裂隙巖溶含水巖組,地下水動態受降水及人工開採影響明顯。截止2012年底,地下水日均開採量為5.2萬 m3,接近繫統允許開採量5.79萬 m3,處于採補平衡狀態。本文在充分利用前人研究資料的基礎上,通過對牟汶河脩建攔河壩,河水位抬高引起的巖溶水補給條件變化的研究,確定該含水繫統尚具有開採潛力,其潛力主要來源于地錶水入滲補給。通過研究計算,目前該含水繫統還具有約 2萬 m3/d 的開採潛力。

Tai’an urban-Jiuxian karst water system is located at the foot of the southern Mount Tai in Shan-dong Province,it is a monoclinal structure water-bearing system with two water sources in urban and Jiux-ian.It is higher in the north than in the south,covering an area of 1 1 2 square kilometers.The water-bearing stratum of the system are predominatly Quaternary,Cambrian and Ordovician,with a large area of Archaean igneous rocks of Taishan group in the south and the north.The tectonic unit is a part of Luxi anticline in the western Tailai fault subsidence basin.Faults include the NE-trending Taishan,Culaishan and Jiezhuang faults,and NW-trending Honggou,Panghe and Daidaoan faults.The water bearing formation includes a pore aquifer in uncosolidated Quaternary sediments and a karst bedrock fracture aquifer in the Cambrian-Or-dovician carbonates.The groundwater is obviously affected by precipitation and artificial exploitation.By the end of 2012,the exploitation of groundwater was 52 thousand cubic meters per day,approaching the allowa-ble with drawal limit of 57.9 thousand cubic meters,which is the equilibrium of exploitation and recharge-ment.Relying on the previous data,changes in the karst water recharge due to the barrage of Muwen River was studied.Results indicate that the system still has potential for exploitation due to recharge by surface water,and about 20 thousand cubic meters water per day are allowed to be exploited in the water-bearing system.
