【摘要】 本文通过对河床渗并集水流网与隔水边界附近水源井集水流网的对比分析，应用渗流理论中的镜象法与势叠加原理，推导出了薄含水层条件下井底进水河床渗井的出水量计算公式．经验证，公式精度令人满意，可满足实用要求，而且简单直观．文中还强调了出水量计算中应注意的几个问题．更多还原

【Abstract】 Based on the analysis of flow-net of collecting water of the infiltration well on riverbed and resource well in the vicinity of confining boundary, and using the infiltrationflow theory of underground water, this paper presents the equation for calculating yieldsof the bottom intake infiltration well on riverbed in thin aquifer. It has been tested and verified by concrete engineering example with satisfactory precision, and can be applied satisfactorily for practice, intuitively and simply. Besides,some questions about calculat-ing yields of collecting water have been stressed.更多还原
