摘　　要：对大型人工运河跌水工程群开展汇流口通航水流条件分级研究,可筛选出若干典型跌水工程作为重点研究对象开展数值模拟或物模试验研究,并为后续跌水工程群的全面通航安全评价提供技术支撑。跌水工程汇流口通航水流条件主要与汇流比、汇流角、流量、堰宽、干渠水深等量化影响因子及汇流口布置形式等相关,依据量化影响因子构建的通航水流条件复杂度分级评价指标可定量反映汇流口通航水流条件的复杂程度。采用最小-最大标准化法及K均值聚类分析法,依据评价指标将江淮沟通段跌水工程群分级为4个类别,再从全部50座跌水工程中筛选出18座通航水流条件复杂度较大、汇流口布置形式代表性较好的典型跌水工程作为重点研究对象,典型跌水工程在各汇流口布置类型中的分布较均衡。The classification of the navigation flow conditions at the confluence of a large-scale water drop project group on an artificial canal can pave the way for the selection of several typical water drop projects as the key research objects for numerical simulation or physical model tests and provide technical support for the subsequent comprehensive navigation safety evaluation of the water drop project group.The navigation flow conditions at the confluence of a water drop project mainly depend on quantitative influencing factors,such as the confluence ratio,confluence angle,flow,weir width,and water depth of the main channel,and the type of the confluence layout.The evaluation index for classifying the complexity of navigation flow conditions constructed on the basis of the quantitative influencing factors can quantitatively reflect the complexity of the navigation flow conditions at the confluence.Using the minimum-maximum standardization method and the K-means cluster analysis method,the paper classifies the water drop project group in the Yangtze-Huaihe communication section into four categories according to the evaluation index.Then,it selects 18 typical water drop projects with highly complex navigation flow conditions and highly representative types of confluence layouts from the 50 water drop projects as the key research objects.These typical water drop projects are in a relatively balanced distribution in various types of confluence layouts.
