在潮汐河口地区,采取疏浚方法来增加碍航浅滩航槽的水深,使其在满足已定船型的航行吃水深度前提下,通过深入分析影响通航的各种水文要素,尽可能设法减少控泥量,降低疏浚工程费用,这是优化航道设计方案的重要因素之一。本文结合汕头老港区的水文特性、乘潮水位、候潮时间(天数),以及航道洄於模型试验的研究结论等资料,对在工程可行性研究中,所提出的通航设计水深及航道设计尺度,作了进一步论证。
In the tidal estuary area, dredging methods are adopted to increase the depth of the forcibly blocked shoal slot so that it can meet various hydrological factors that affect the navigation, and try its best to reduce the amount of mud control , Reduce dredging project costs, which is one of the important factors to optimize the design of the waterway. Based on the hydrological characteristics, the tide level, the time of waiting tide (days) and the research results of the waterway migration in the model test in Shagang Old Port, this paper analyzes the water depth and the design of the waterway proposed in the project feasibility study. Scale, made a further demonstration.
