长江下游地区挖入式港池口门宽度的计算方法

Calculation methods for the channel width of excavated-in harbor basin in the Yangtze River region

受长江航道的自然地形水深和南京长江大桥通航净空的限制,港口物流服务的腹地纵向延伸和广域化辐射受到较大阻碍,因此,在长江下游河段新建的港口宜尽量兼备承接上游来船转运出海的功能和由海轮转驳江轮的功能。现行规范对于挖入式港池宽度已有较为详细的规定,但对于船舶进出于两码头之间的挖入式港池口门宽度还没有明确的规定和要求,从航道角度出发,引入航行漂角和偏航角概念,着力于阐述船舶进出于两码头之间的挖入式港池口门宽度的计算确定方法。

Due to the limitation by the natural terrain depth of the Yangtze River channel and navigable clearance of Nanjing Yangtze River bridge,the longitudinal extension and radiation of port logistics service are seriously held up.Thus the newly built port in the downstream of the Yangtze River shall be able to undertake the transshipment of vessels from the upstream to the sea and then to the river.The present code includes detailed stipulations on the width of the excavated-in basin,but there aren＇t any stipulations yet on the entrance width of the excavated-in basin which is between two wharves.From the angle of navigation channels,drift angle and yaw angle,this paper focuses on the calculation and determination methods for the entrance width of excavated-in basin between two wharves.
