摘要
为推进归湖韩江特大桥项目建设,根据工程实际情况,结合GB 50139—2004《内河通航标准》和交通部行业联合科技攻关项目(2003-335-343-42)成果,论证旁拖、斜交、横流、紊流等因素对特大桥通航净宽的影响,最终确定其通航净宽尺度。并为类似跨航道建筑物通航净宽设计提供实例参考和具体计算模型。
According to the actual situation of Guihu Hanjiang grand bridge project, and based on the Navigation Standard of Inland Waterway （GB 50139-2004） and relevant research achievements by the Ministry of Transport （ No. 2003-335-343-42）, we demonstrate the influence of the towed alongside, oblique cross, cross current, and turbulent flow on the navigation clearance dimension of Guihu Hanjiangr grand bridge, and determine the navigation clearance dimension at last. It provides reference example and specific computational model for similar designs of crossing channel structure.
