井抽水时,水位降落漏斗的水量均衡关系是渗流理论中一个重要的实际问题。对这一关系认识的不同,将直接影响对地下水资源中地下迳流量的认识。例如,地下迳流能否被抽水井所抽取,井抽水时能否达到稳定状态等。对此,笔者提出看法。一、井抽水时的流网分析当井在含水层中抽水时,天然含水层的流网便发生根本变化。等水位(或压力)线和流线都改变了天然的平缓状态(见下图)。
Well pumping, the water level falling funnel water balance is an important practical problem in seepage theory. The different understanding of this relationship will directly affect the understanding of the underground flow of groundwater resources. For example, whether the underground flow can be extracted by a pumping well or whether the pumping can reach a steady state when pumping well. In this regard, I make a comment. First, the flow network analysis of well pumping When wells pumping water in the aquifer, the natural aquifer flow network has undergone fundamental changes. Equal water level (or pressure) and flow lines change the natural flat state (see below).
