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。
Pipeline flow is a unique geomorphic hydrological phenomena in the karst region. It is a typical manifestation of dual karst karst medium and binary structure, and has very particularity and complexity. In this paper, the characteristics of karst landform and recharge of pipeline flow are introduced. The hydrodynamic characteristics of pipeline flow are expounded. Hydrological characteristics of pipeline flow are considered to be controlled by pipeline structure, supply mode and route. This paper focuses on the methods and analysis conclusions of using underground water reservoirs for water pulse test to analyze the structure of underground river system, the ratio of pipe water diversion and hydrodynamic parameters, which has certain theoretical significance and practical value for further research on karst pipe flow.
