摘　　要：供水管网的漏损评定是管网漏损控制的重要内容。现有漏损评定手段主要为《城镇供水管网漏损控制及评定标准》中提出的“水量平衡表”,分别针对单个区域内的水量进行平衡分析,难以解决漏损控制中“主要区域在哪”“主要矛盾是什么”的问题。基于对现行水平衡分析方法的原理及问题探讨,在厘清管网用水组分构成及空间分布关系的基础上,提出了基于分区“组分-空间”关系分析的二元水平衡分析方法,同时揭示漏损组分构成及不同区域间的水量传递与平衡关系。所提出的方法对提高管网数据分析管理的全面性、漏损控制的针对性具有指导意义。Leakage assessment plays an important role in the management of water distribution networks.Most current leakage assessment methods in China are based on the'water balance table'proposed in the Standard for zwater loss control and sssessment of urban water distribution system,which carries out balance analysis in each area respectively,and it is difficult to directly answer‘where the main area is'and'what the main contradiction is'.Based on the discussion of the principles and problems of the current water balance analysis method,and on the basis of clarifying the composition and spatial distribution relationship of water usage in pipe network,a dualistic water balance analysis method is proposed based on the'component-space'relationship of water usage,thus the components of leakage and the water transfer and balance relationship among different regions can be simultaneously revealed.The proposed method has significance in improving the comprehensiveness of data management of and the purposiveness of leakage control.
