针对海图上航道水深数据稀少、进行乘潮进港分析不准确的不足,本文提出了基于高精度瞬时水深模型的乘潮进港分析方法。在海图水深的基础上,融入高密度多波束水深数据,共建高精度静态水深模型,并进一步精化水位预报,形成高精度的瞬时水深模型;然后,采用分段测试的方法,分析航线可行性,并求取乘潮进港时间窗口。实验结果表明基于高精度的瞬时水深模型能够获得更准确的乘潮进港出发时间窗口,可提高航道通航能力。
In view of the scarcity of water depth data in the navigation channel and the inaccurate analysis of the inflow into the harbor by the influx of tide, this paper presents a new approach to analyze the influx of inbound water based on the high-precision instantaneous water depth model. Based on the depth of chart, high-density and multi-beam depth data are integrated to build a high-precision static water depth model and to further refine the water level forecast to form a high-precision transient water depth model. Then, by using the subsection test method, Feasibility, and seek the influx of time into the window of time. The experimental results show that the high-precision instantaneous water depth model can obtain a more accurate time window for departure of inflow to the harbor, which can improve the navigation ability of the navigation channel.
