摘要
本文采用连续介质水电比拟法,对不完整河旁三维井流与完整河旁二维井流作了对比研究。结果表明,当其他条件相同时,前者水井出水量只能达到后者出水量的80％左右;实测的两类流场图,显示出三维井流与二维井流的许多重要特征和区别,对此作了详细对比分析,阐明了流量显著变小的机理;指出不完整河旁井流问题按三维流计算的必要性;对当前工作提出了重要且可行的建议。
By means of water-electricity analogy method fot a continuous medium , this paper studies the thtee -dimensional well-flow in a incomplete well beside a river. The results show that the well -water outflow of the former can only reach 80% of the later,when other conditions are indentical. Measured real flow field map for these two well flows shows many important features and differences between the two and three-dimensional well -flows. In this paper, detailed analysis and contrast are made, which expounds the mechanism in which the flow turns into small. The author points out that it is necessary to solve the equation of incomplete well -flow beside a river according to three dimensional well -flow method.
