曹妃甸中区一港池口门拓宽方案研究

曹妃甸中区一港池是曹妃甸港区的重要作业区,港池内已建有20万t级泊位,现状航道等级规模为10万t级,限制了整个港池的发展,而航道等级的提升,口门尺度成为了最重要的制约因素。考虑到港池内的掩护效果,本文提出了在不拆除既有防波堤的前提下,口门位置处的拓宽改造方案,并结合模型试验,验证口门改造方案的合理性。

Study on the widening scheme of one port gate in caofeidian central district

As an important operation zone in the central area of Caofeidian harbor,Basin No.1 includes the berths for ships up to 200,000 DWT,but the channel for ships up to 100,000 DWT restricts the development of the whole harbor basin.The entrance size serves as the most important factor that limits the upgrading of a channel.By considering the shielding effect of the harbor basin,an entrance widening plan based on the existing breakwater is put forward,and a model test is adopted to verify the reconstruction plan.
