摘要

本文以郑州龙湖工程拱形闸为例,阐述了拱形闸在大跨度景观河道上的应用。大跨度、低水头、闸门门顶过水、闸墩少、兼顾河道景观是本工程的设计难点。通过水工模型试验研究了拱形闸门流态以及各工况下的压强分布;采用三维有限元模型和流激振动分析方法,论证了闸门门顶溢流、闸门局部开启运行及启闭过程中的安全性及可靠性。
        Taking the arch gate of Longhu project in Zhengzhou as an example, this paper expounded the application of arch gate in large-span landscape river. The design difficulty of this project is large span, low head, gate top over water, less piers, and river landscape. Through hydraulic model test, the flow pattern and pressure distribution of arch gate under various working conditions were studied. The safety and reliability of overflow of gate top, partial opening and closing of gate were demonstrated by using three-dimensional finite element model and flow-induced vibration analysis method.
