天津新港延长防波堤的减淤效益研究

本文以较丰富的原观资料、室内试验为主要依据,同时参考过去本港的有关研究成果,对影响港口回淤率的一些主要因素(如港池的深水面积、航道宽深、入港含沙量、泥沙动水沉速等)进行分析,对防波堤两种延伸长度的减淤效益进行了论证。从一个侧面为天津新港防波堤延伸长度的确定提供了依据。

Study on the Benefit of Siltation Minimization of Extending the Breakwaters of Tianjin Port

Basing on a large amount of data and the laboratory studieies and refering to the previous researches on this port , the main factors effecting the siltation rate (such as the area of deep water basip, widthe and depth of the channel the concentration at the entrance of the port , and the settling velocity of the suspended sediment , etc ) are analyzed , and the benefits of sil -tation mimmization from extending the breakwaters of Tianjin port are proved in this paper .It provides the basis for defining the extended length of the breakwaters.
