天津南港工业区通海航道泥沙水力特性试验研究

Experimental study of sediment hydraulic characteristics on Tianjin Nangang seaward channel

规划南港工业区拟建一条通海航道,为确定航道底质泥沙属性,为航道工程的相关研究与建设提供技术依据,根据南港地区已有资料,对航道内现场取样的底质泥沙进行了水动力特性试验,并与附近天津港和黄骅港航道泥沙特性进行了类比。结果表明:南港工业区泥沙"活跃性"比粉沙质海岸性质的黄骅港泥沙弱而又比天津港强,泥沙特性与天津港泥沙更接近,应划定为淤泥质海岸。

A seaward channel is planned in Nangang industrial zone. In order to determine the bottom sedi-ment properties and provide technical basis for waterway engineering research and construction, based on the exist-ing data of Nangang District, the sediment water dynamic properties were tested and compared to that of the Tianjinport and Huanghua harbor. The results show that the sediment active degree in Nangang industrial zone is weakerthan that of the silty coast in Huanghua harbor, and stronger than that of Tianjin port, and the sediment characteris-tics are more close to the sediment in Tianjin port, which should be designated as the muddy coast.
