天津中心渔港进港航道尺度论证与航道泥沙回淤研究

Research on approach channel dimension of Tianjin central fishing port and sediment siltation

天津中心渔港作为一个新建海港,航道的选线恰当与否直接影响到工程投资及建成后的维护费用。为此,在充分认识中心渔港所在位置的自然条件的基础上,对进港航道尺度进行了论证,进而对航道拟选线路方案进行了泥沙回淤分析。研究表明,选择航道长度相对较短、航道走向和水流夹角尽可能小的航线可以明显减小工程后泥沙回淤强度。

Since Tianjin central fishing port is a newly-built harbor, whether the waterway is designed properly or not will directly affect the engineering investment and the maintenance charge of port area after construction. Therefore, based on fully understanding of natural condition in the position of central fishing port, demonstration for approach chan- nel dimension and research on sediment siltation for several channel routes are conducted. Research shows that if the I length of channel is relatively short and the angle between waterway direction and water flow is as small as possible, then sedimentation intensity can be obviously reduced.
