大型船舶进出港安全乘潮计算模式的研究

A Study on Calculation Modes of Large Ships safely Entering or Leaving Harbor in Higher Tide

本文从分析大型船舶乘潮作业的尺度关系着手,对建立大型船舶进出港安全乘潮通航计算模式进行详细的技术探讨。用所建立的计算模式对长江口北槽一年702个潮的实例分析计算表明,长江口地区的理论通航能力较目前的实际通航能力要大得多,由此可见,开发长江口的通航潜力大有可为。

Begining with an analysis of scale re ltionship of large shipsoperating at high tide, the paper discusses technically the establi-shment of calculation modes of large ships entering or leavingharbor at high tide. Using the established modes, the author makes analysis andcalculations of the 702 tides in Bei Cao, at the entrance of theYangtze River, in the year. The result shows that the navigablecapacity at the entrance of the Yangtze River in theory is muchlarger than the present capacity. Thus it is prospective to tap thenavigable potentials at the entrance of the Yangtze River.
