摘要
基于MIKE 21软件建立引江济淮工程山丘区支流苦驴河、高桥河、尹河、界河、柯坦河平面二维水动力学模型,选用非结构化三角形网格模型进行洪水演进模拟,重点研究支流发生100年一遇超标准洪水或5年一遇洪水,分别遭遇干流最高或最低通航水位时,干流航道内最大横向流速情况,为引江济淮工程航道设计提供参考依据。
Based on the MIKE 21 software,a two-dimensional hydrodynamic model was established for the tributaries of Kulvhe,Gaoqiaohe,Yinhe,Jiehe and Ketanhe in water transfer project from the Yangtze River to Huaihe River.This paper used unstructured triangular mesh model to simulate flood routing and focused on the100-return-year or 5-return-year tributary flood events.This paper analyzed the maximum transverse flow velocity in main stream channel when they encountered the highest or lowest navigable water level.It woud provide theory basis for waterway design.
