中小型河谷中辐射井的计算公式组

Formula Group for Calculating Radiation Well in River Valley of Medium and Small Size

本文用点源原理阐述中小型河谷辐射井的有界条形含水层内的点源降深场,沿辐射滤管长度方向的进水流量变化,滤管各点源引起降深的迭加,辐射管诱发河流补给所造成的负降深场,辐射井出水量与降深的关系,以及它们的计算公式组。

Point source drawdown field in boundary strip aquifer of radiation well in river valley of medium and small size, the variation of inflow water along the lengthwise direction of radiation, superimposition of drawdown induced by point sources of screen pipe, field of negative drawdown resulted from recharge of rivers induced by radiation pipe, the. relationship between yield of radiation well and drawdown and formula group for calculating them, are all expounded with the principle of point source in this paper.
