基于河流特性的南水北调倒虹吸行洪口门分析

Based on the river characteristics of the inverted siphon flood discharge opening in South to North Water Diversion Project

南水北调中线总干渠在河南境内与众多河流交叉, 在对总干渠第? 亚段黄河北至漳河南段河渠交叉渠道倒虹吸穿越的33 条大型河流特性分析的基础上, 针对平原排水河道、山丘区宽浅型河道、窄深型河道、城市排洪河道等不同类型的河道及洪水特, 提出了倒虹吸行洪口门布置要点, 并结合洪水调算确定了科学合理安全经济的行洪口门宽度与体型, 对类似工程的设计也可以起到参考作用。
