摘要
唐山曹妃甸港区建港期间,纳潮河一直呈封堵状态,2016年纳潮河局部开通,文章采用现场监测和数值模拟方法对唐山港曹妃甸港区纳潮河局部开通后流态进行了监测与反演,并对总体规划实施后流场进行了预测,对纳潮河开通前后流场变化进行了分析,结果表明纳潮河开通后纳潮河两侧随涨落潮进行流向会有较大变化,涨潮期间水流会从东侧老龙沟航道方向向中区二港池流入,落潮时会反向流出,且流速会有所增加,港池流速增幅在0.02~0.32 m/s之间,增加比率可达到150%以上,给船舶靠离泊可能会带来一定的安全隐患,需要引起关注。
During the construction of Tangshan Caofeidian port area,the Nachao River had been blocked up until it was partially opened in 2016.In this paper,the flow pattern after the opening of the Nachao River was inverted by means of field monitoring and numerical simulation,and the flow field after the implementation of the master plan was predicted.The flow pattern changes at different stages of the Nachao River were analyzed.The results show that the flow direction of both sides of Nachao River will change greatly with the fluctuating tide after the opening of the Nachao River.During the flood season,the flow will flow from the Laolonggou channel at the east side to the Second harbour basin.When the tide falls,the flow will flow backwards,and the flow speed will increase.Flow velocity in harbour basin will increase between 0.02 m/s and 0.32 m/s,and the increase rate can reach 150%.On the other hand,it may bring some potential safety hazards to the berthing of ships,which should be paid attention to.
