| 摘 要： | 岩溶含水介质由管道、裂隙与孔隙３类空隙介质组成，它们对地下水流动具有不同的贡献。简述了当前岩溶水的几种主要定量评价方法，提出折算渗透系数尺概念，建立了岩溶三重空隙介质地下水流统一的控制方程，引出管道与裂隙在达西流与非达西流状态下的渗透系数与折算渗透系数的表达式，从而将达西流与非达西流耦合在一个模型中。本文提出岩溶三重介质地下水流的模拟方法，并给出理想模型的模拟结果。

| Abstract: | Karst media is normally combinated with three kind voids of tube, fissure and pore,which have different effects on the groundwater flow.A brief of calculated method in karst groundwater is introduced. The author presents a conception of equivalent hydraulic conductivity (EHC) and derives an expression form of EHC in the different flow conditions of non-Darey flow.A unified governing equation if karsi=tic triple void media is established. Darey flow and non-Darcy flow is coupled into one model.The effective simulation method is presented a simulted results of ideal model is shown in the paper. |
