河道平面变动对引汉济渭二期工程穿泾河倒虹吸布置的影响分析

The Influence and Analysis on the Inverted Siphon Layout of Jinghe River in Phase Ⅱ Project of Diversion from Han River to Wei River due o the River Plane Changes

泾河是渭河泥沙的主要来源,受水沙等多种自然因素影响,泾河下游、特别是张家山至入渭口段河道摆动较为频繁。本文结合引汉济渭二期工程穿泾河倒虹吸布置,分析河道平面变动对穿河建筑物布置的影响,建议将倒虹吸左滩部分、滩槽分界点以东水平长度524 m段(即C1~D4段)按主河槽埋深控制,以减轻河道平面变动对工程安全的影响。其分析方法可为类似工程提供参考。

Jinghe River is the main source of the sediment of Weihe River. It is affected by various natural factors such as water and sediment. This article combines the inverted siphon arrangement of the Chuanhe River in the second phase of the Hanji-Wei River Project to analyze the influence of the change of river plane level on the layout of the buildings passing through the river. Section ~ D4) is controlled according to the burial depth of the main channel to mitigate the impact of river level changes on project safety. Its analysis method can provide reference for similar projects.
