摘 要:小型灌溉渠道量水设备类型很多,在生产实践中经常遇到如何选型的问题。总结了目前常用几种量水设备的技术特性,在此基础上提出一种基于层次分析法(AHP)的小型灌溉渠道量水设备选型方法。该方法以量水设备选型为目标层,以测流范围、淹没度、测量精度、工程造价、测流及管护方便程度为准则层,以常用的量水设备为方案层。分析结果表明,针对我国南方大中型灌区,梯形断面斗农渠量水设施的优选顺序为分流量水计、圆柱形量水槽、量水槛、矩形无喉段量水槽、巴歇尔量水槽。优选结果对以上所述地区灌区斗农渠量水设备的选择具有一定的指导价值。There are many types of water metering equipment for small irrigation canals.A summary is made on technical features of some water metering equipment,which is used as the base to select metering equipment for small irrigation canals by means of Analytic Hierarchy Process(AHP).The method uses the type of metering equipment as the target,scope of flow measurement submergence ratio and accuracy,cost,flow measurement and convenience of operation and maintenance as the criteria and meters that commonly used as the options.The evaluation results show that the preferable sequence of metering facilities for trapezoidal cross-section lateral canal should be distributary water meter,cylinder-shaped measuring flume,water metering cage,rectangle cut-throat water measuring flume and Parshall flume,which can be used as guidance for the selection of metering facilities in large and medium irrigation districts in southern part of China.
