长江口北槽12.5 m深水航道边坡自然水深利用标准研究

Natural water depth utilization standard of the Yangtze Estuary 12.5 m deep-water channel slope

针对长江口深水航道大型船舶交会需求的增加所带来的通航需求与深水航道宽度资源之间日益突出的矛盾,开展深水航道边坡自然水深利用标准研究,基于尽可能减少对航道维护的影响和利用自然现状水深的原则,采用实测资料统计分析与理论计算的方法,提出边坡自然水深利用宽度、深度和区段,为相关部门开展实船试验及保障措施研究提供依据,并在边坡自然水深利用总体方案中得到充分应用。

In view of the increasingly prominent contradiction between navigation demand and deep-water channel width resources brought by the increase of large-scale ships’rendezvous demand in the Yangtze Estuary deep-water channel,we study the utilization standard of the natural water depth of the deep-water channel slope.Based on the principle of minimizing the impact on channel maintenance and utilizing the natural water depth,we propose the width,depth and,section of the slope’s natural water depth utilization by using the method of statistical analysis of the measured data and theoretical calculation.It provides a basis for relevant departments to carry out ship tests and research on support measures,and is fully applied to the overall scheme for the utilization of the slope’s natural water depth.
