摘要
本文提出了失水带迟后反应原理和延迟给水理论模型，它考虑了失水带毛细管和介质阻力对流动的影响，其水位、水头解能自然地再现Ｗａｌｔｏｎ“三阶段”型曲线。纽曼模型解仅是本法的一特例，因它未反映失饱和带的影响，其水位过程解型式与实测“三阶段”型相反。考虑了测壕（井）对流动影响的方法能获得更符实际的含水层参数值。文中并首次研究了在孔隙—裂隙流动中延迟释水的机制，提出“耦合滞后”原理，并经实例验证本模型对弱岩溶潜水流的适用性。
A theory of delayed response in drainage area above lowered water table is proposed toconsider the effect of capillarity and media resistance upon flow,It’s solutions to water levelprocess can perfectly reveal the pattern of“three stage curve ” concluded by Walton.Neuman’s model only is a special case and it’s solutions display the pattern opposite toWaltan’s. The coupling delay principle for pore-fissure media is also presented.The methodis verified through practice and is applicable to unconfined flow in less karstified stratum.
