摘要
针对跨河桥群引发的通航标准问题开展了初步的探讨。基于桥洞纵深长度和船舶通视角等对船舶安全通过桥区的影响,以及船舶碰撞角和桥群斜交等对桥梁净宽要求的影响,提出了限制桥洞纵深长度等的建议和调整桥群净宽的计算方法。
This paper discussies the navigation standard of bridge group crossing river. Based on both the influence of bridge opening depth and the ship eyeshot angle on the navigable safety, and the influence of the ship collision angle and the oblique bridges on the bridge clear span, a proposal to limit the bridge opening length and the calculating method to adjust the bridge clear span are presented.
