摘　　要：以岚山港南作业区为例,分析研究了环抱式港池建成初期船舶乘潮进港的调度问题。岚山港南作业区进港航道轴线与涨、落潮主流流向夹角较大,存在近口门航道段横流较大的问题;涨潮阶段横流普遍强于落潮阶段横流;涨潮阶段最大横流出现在口门外沿航道轴向400 m处。根据统计结果分析建立涨急流速和潮差的关系以及涨潮阶段设计乘潮水位流速与涨急流速的关系,然后通过查询潮汐表信息推算水深和横流,从而为确定船舶乘潮进港时间提供科学依据,达到船舶调度目的。Taking the southern operating area of Lanshan port as an example, this paper analyzes the scheduling of ship＇s entering the port in higher tide at the initial stage of the surrounding basin. There is a larger angle between the channel axis of the southern operating area of Lanshan port and the flow direction of mainstream of flooding and ebbing tides, resulting in a larger cross-flow in the channel near the entrance. The cross-flow during the flood phase is larger than that during the ebb phase. The largest cross-flow during the flood phase presents at 400 m along the channel axis outside the entrance. According to statistic results, the relationship between the maximum velocity during the flood phase and tidal range and relationship between the designed tide-bound water level during the flood phase and the maximum velocity during the flood phase is established and then water depth and cross-flow are calculated by inqurirying the tide table, so as to provide a scientific basis for determinating the time of ship＇s entering port in higher tide, and thus achieve the goal of ship scheduling.
