即墨市宝龙泉水文地质条件调查与分析

通过资料收集、专项地质测量、水文地质调查与测绘、水文地质物探、水文地质钻探、钻孔抽水试验、水质分析试验和综合研究等技术方法对宝龙泉区域水文地质条件进行了勘查,对泉的成因、汇水面积、补给量和流量进行了初步的分析和探索,结果显示:泉区内发育的7条近南北和近东西向的断裂异常构成了宝龙泉泉脉的构造格局,经钻探验证,3条断裂透水性好,含水丰富,其中DF1-3和DF3-4断裂为宝龙泉的主要泉脉通道;在水位标高53. 07 m时,泉水自流的流量为296. 76 m^3/d;泉水的矿化度为0. 582 g/L,水化学类型HCO3·SO4-Ca型。地下水水质主要类型分类为Ⅱ~Ⅲ类,均受不同程度的污染,主要适用于集中式生活饮用水水源及工、农业用水。按地表汇水面积和断裂形成的区域面积分别计算,可估算出宝龙泉流量平均为303. 78 m^3/d和337. 14 m^3/d。研究结果可为宝龙泉区域泉水的保护和开发利用提供依据。

Investigation and analysis of hydrogeological conditions in baolongquan,jimo city

Through the data collection special geological surveying hydrogeological investigation and surveying and mapping hydrogeological exploration hydrogeology drilling borehole pumping test water quality test and analysis,and the comprehensive technical methods,such as the treasure to longquan regional hydrogeological conditions for exploration,on the cause of the spring water catchment area of recharge and discharge has carried on the preliminary analysis and exploration,the results showed: spring development in the area of 7 nearly north-south and nearly east-west fracture abnormal constitutes the treasure to longquan springs pulse tectonic framework,it has been verified by drilling,three fracture permeability is good,rich water,including DF1-3 and DF3-4 fracture is the main stream of treasure longquan vein channels;At the water level elevation of 53. 07 m,the spring flow of spring water is 296. 76 m^3/d. Spring water salinity of 0. 582 g/L,hydrochemical type HCO3,SO4-Ca ~ for main types of groundwater water quality classification,are affected by different degree of pollution,mainly suitable for centralized drinking water and water for agriculture and industry according to the water catchment area and the fracture form was calculated respectively,and the area to estimate the treasure longquan flow with an average of 303. 78 m^3/d and 337. 14 m^3/d the results can be used as protection of treasure longquan area springs and provide basis for development and utilization.
