深圳至中山跨江通道矾石水道远期预留航道等级论证

Demonstration of long-term level of Fanshi waterway in Shenzhen-Zhongshan Passageway crossing the Pearl River

探讨了珠江口矾石水道在远期深圳至中山跨江通道(下称"深中通道")投入使用时所需预留的通航等级,以避免深中通道影响珠江口两岸各港船舶通航的安全、顺畅。综合考虑珠江口现状通航条件和远期港口规划,初步提出矾石水道预留10万吨级通航等级的必要性,并利用数值模拟、综合物探等手段,重点从矾石水道的深槽稳定性、通航水流条件、航道可挖性和航道可维护性进行分析论证,同时对比国内典型规模化港口,阐明港口吞吐量规模对航道资源的要求,提出矾石水道预留航道等级应考虑的因素,最终认为矾石水道预留航道等级为10万吨级是必要的、可行的。

This paper mainly explores the navigable long-term level of Fanshi waterway required for the Shenzhen-Zhongshan Passageway crossing the Pearl River Project(hereinafter referred to as“S-Z Passageway”)in order to avoid the influence of the S-Z Passageway on the safety and smoothness of the navigation of vessels on both sides of the Pearl River estuary.The paper comprehensively considers the current navigable condition of the Pearl River estuary and the long-term ports planning,and puts forward the necessity of reserving the navigable grade of 100,000-ton class for Fanshi waterway.Using numerical simulation and comprehensive geophysical prospecting,we analyze and demonstrate the deep trough stability of Fanshi waterway,water flow conditions,channel dredging and channel maintenance.At the same time,compared with the typical large-scale domestic ports,we clarifies the scale of the port throughput requirements for channel resources,and put forward the factors which should be considered in demonstration of the long-term level of Fanshi waterway.We think that it is necessary and feasible for Fanshi waterway to reserve channel level of 100,000-ton class.
