摘　　要：随着国民经济的发展和生活水平的日益提高,人民群众对优美水生态环境的需求亦日益增长。在城市生态蓄水工程中,钢坝闸因其没有上部结构,可形成宽阔水面和跌水瀑布,营造出良好的生态水景观,同时还具有安全稳定、过流能力强、使用寿命长等优点,具有广泛的应用前景。但当前已建的大部分钢坝闸跨度较小,且沿河道全断面布设,大跨度、高水头的钢坝闸设计较少。本研究根据海河流域主槽型河道的特点,提出了沿河道主槽布置大跨度钢坝闸、控制设备布置于堤顶外侧的典型设计方案,相关结构设计、地基处理及钢闸门设计,对同类型河道中布置钢坝闸具有一定借鉴意义。With the development of national economy and the improvement of living standards,people's demand for a beautiful aquatic ecological environment is also increasing.In the urban ecological water storage project,the steel dam gates can create wide water surfaces and waterfalls due to their lack of superstructure,creating a good ecological water landscape.At the same time,they also have the advantages such as safety,stability,strong flow capacity,and long service life,and have broad application prospects.However,most of the existing steel dam gates have relatively small spans and are arranged across the entire river section,and the design of large span and high head steel dam gates is less common.According to the characteristics of the main channel of Haihe River basin,this study puts forward a typical design scheme of arranging large-span steel dam gate along the main channel of the river,with control equipment placed on the outside of the embankment.The related structure design,foundation treatment and steel gate design have certain reference for the arrangement of steel dam gates in similar river channels.
