【摘要】：合理设计开采方案对傍河水源地地下水资源开发具有重要意义。以德惠典型傍河地下水水源地为研究区,在查明研究区水文地质条件的基础上,以管井为例,运用解析法确定了最佳开采方案和水源地地下水允许开采量,并对最佳开采方案的合理性和可靠性进行了分析。结果表明,当开采井沿河流呈直线形单排布井方式,井数为12眼,井河距离为200 m,井间距离为150 m,单井开采量为2 960 m~3/d,总开采量为35 520 m~3/d时,取水保证程度较高,面对河流突发性污染具有一定的抵御能力,不会对区域水环境和其他用户造成较大影响。
[Abstract]:Reasonable design of mining scheme is of great significance to the exploitation of groundwater resources in the riverside water source area. Taking the typical groundwater sources along the river in Dehui as the study area, on the basis of finding out the hydrogeological conditions in the study area and taking the tube well as an example, the optimum exploitation plan and the allowable exploitation of the groundwater in the water source are determined by analytical method. The rationality and reliability of the optimal mining scheme are analyzed. The results show that when the wells along the river are arranged in a straight line, the number of wells is 12, the distance between wells is 200 m, the distance between wells is 150 m, the extraction capacity of single well is 2 960 mm / 3 / d, and the total recovery is 35 520 m / 3 / d, the guaranteed degree of water intake is higher. In the face of sudden pollution of rivers, it has a certain ability to resist, and will not have a great impact on the regional water environment and other users.
