| 摘 要： | 经过对研究区的水文地质条件进行分析,设计了3种开采方式:廊道、辐射井、渗流井。建立研究区的地下水流三维数值模拟,计算出廊道、辐射井、渗流井的允许开采量分别为:0.65、0.68、1.18万m3/d。通过对比分析,表明渗流井与相同技术条件下的廊道及辐射井相比,出水量大,供水保证率高,并且在建议开采量下含水层的水位降深在允许范围内。最终选定渗流井作为张家川水源地地下水的开采方式,对研究区地下水的开发利用具有很好的指导作用。

| Abstract: | Based on a brief analysis of hydrogeological conditions in study area, the paper designed three exploiting ways such as gallery, radial well and seepage well. Through setting up three-dimensional numerical model of groundwater in the area, the reasonable yields of gallery, radial well and seepage well are 6500,0and 11800m3/d .Through contrast analysis,the simulation results suggested that seepage well has the most amount of water and the highest water supply guarantee rate and the water drawdown under the reasonable yield should be within the allowable range. The seepage well is finally selected as the exploiting way of Zhangjiachuan water source region, which has good directive function for the development and utilization of groundwater in the study area. |
