薄含水层中大口井井底进水高度的设计

THE DESIGN OF THE BOTTOM INTAKE HEIGHT OF SHALLOW-DUG WELL IN THIN AQUIFER

通过模拟试验结果的分析,提出了薄含水层中大口井井底有效进水高度N_A的概念,并建立了N_A的计算公式,从而解决了在设计从薄含水层中集取河床渗透水与浅层地下水大口井时,井底进水高度的合理确定问题。

Based on the analysis of the result of simulation experiment,and effective intake-height concept;Na has been defind in this paper for the bottom of shallow-dug well in thin aquifer. Also two formulas for calculating Na have been developed. Thus Na can be determined appropriately in designing dug well which collects the infiltration water through river bed or shallow saturated aquifer.
