【摘要】 管道流是岩溶地区特有的地貌水文现象，它是岩溶双重含水介质和二元结构典型表现，具有相当的特殊性和复杂性。本文从岩溶地貌和管道流的补给特征入手，阐述管道流的水动力特征，认为管道流水文特性是受管道结构、补给方式和路径所控制的。文中着重介绍利用流域上游地下水库进行水脉冲试验分析地下河系结构、管道分水比例以及水动力参数的方法和分析结论，这对深入研究岩溶管道流具一定的理论意义和实用价值。更多还原

【Abstract】 Conduit flow is a special geomorphological and hydrological phenomenon in karst area.Itis representative of dual water-bearing medium structure,and has its specific characteristicsand cornplexity.Beginning with karst geomorphological conditions and conduit flow supply, the paperdiscribes the hydrodynamic characteristics of conduit flow.The characteristics of conduitflow are controlled by the structure of conduit,the supply patterns of conduit flow and theflow path.A pulse test was applied with the aid of a subterraneans reservior on the upperreach of a basin to analyse underground river structure,calculate discharge proportion in con-duit and hydrodynamic parameters.It is of theoretical and practical significance in research onkarst conduit flow.更多还原
