摘要
深圳至中山跨江通道(简称“深中通道”)地处珠江中游核心区域,其跨越的珠江口是我国水上运输最繁忙、船舶密度最大的水域之一,其桥梁段总长约17 km,采用大跨径方式跨越伶仃航道、龙穴南水道和横门东水道等多条重要航道,项目建成后成为永久跨海建筑物,改变了桥区水域原有的通航环境,需要充分发挥桥区航标的助航效能,保障桥梁和船舶航行安全。目前国内外现行规范针对桥梁助航标志主要是原则性要求,对于大型跨海桥梁桥区通航环境复杂、标志设计及安装限制条件诸多的情况,原则性要求显然缺乏实践指导意义。以深中通道桥区航标的设计方案为例,针对大型跨海桥梁主桥段和非通航孔桥段不同的助航需求,分析影响桥区助航标志设计的主要因素,提出大型跨海桥梁助航标志设计过程中存在的主要问题以及相应的解决方案,通过桥梁助航标志和水上助航标志的有效衔接最大程度发挥助航效能,并为行业规范的修订及其他大型跨海桥梁桥区助航标志的设计提供借鉴和参考。
Shenzhen-Zhongshan Channel is located in the core area of the middle reaches of the Pearl River.The Pearl River Estuary it crosses is one of the busiest waterways water areas with the largest ship density in China.The bridge section of the channel,with a total length of approximately 17 km,adopts a long-span design to cross several important navigational channels including the Lingding Channel,Longxue South Channel,and Hengmen East Channel.After the project is completed,it will become a permanent cross-sea structure,changing the original navigational environment of the bridge area waters.It is necessary to give full play to the navigation aids in the bridge area to ensure the navigation safety of bridges and ships.At present,the current domestic and international standards mainly impose principled requirements for bridge navigation aids,which are evidently lacking in practical guidance for the complex navigational environment and numerous design and installation constraints of large-scale cross-sea bridges.This paper takes the design scheme of the navigation aids in the bridge area of the Shenzhen-Zhongshan Channel as an example.Focusing on the different navigational needs of the main bridge section and the non-navigable bridge sections of large-scale cross-sea bridges,it analyzes the main factors affecting the design of navigation aids in the bridge area,and proposes the main issues and corresponding solutions in the design process of navigation aids for large-scale cross-sea bridges.The navigation efficiency is maximized through the effective connection between bridge navigation aids and water navigation aids.At the same time,it provides reference and guidance for the revision of industry standards and the design of navigation aids for other large-scale cross-sea bridges.
