具有弯曲特性河道上桥梁通航宽度的探讨

On Navigable Width of Bridge on Curved Inland River

根据船舶操纵性能,结合水流在弯道上的运动特性,提出影响航道宽度的因素,探讨具有弯曲特性河道上桥梁通航所需要的宽度。论文给出全新的计算方法,并与我国2004年“内河通航标准”中的方法进行比较,指出了“内河通航标准”中计算方法的不足。

According to the manipulation characters of a ships and movement characters of current in curved river, the paper gives some factors affecting the waterway＇s width, and discusses the necessary navigable width of bridge on curved river. Compare the methods in ＂Navigation Standard in Inland River （2004 edition）＂ with the new one given, this paper points out the shortage of the calculating methods in the ＂Navigation Standard in Inland River＂
