With the rapid development of shipping,large ships occupy the channel through the access channel for a long time,thus it is necessary for large ships to set up meeting area in the approach channel.The relevant calculation of meeting area in current norms is not clear.In view of the objective reality of Zhanjiang Port's long course,large scale and complex navigation environment,this paper analyzes the conditions of water depth,wave and velocity in the proposed meeting area based on the survey of the current ship type and scale.This paper puts forward the combined navigation schemes of 300,000 t and 150,000 t ships,calculates the navigation width of the channel under the two forms of unified section and compound section,and determines the length,width,turning radius,design bottom elevation and other parameters of the meeting area，then selects the plane layout scheme of the meeting area with good water depth and proper location.
