华能曹妃甸煤码头项目龙口潮流数值模拟

Numerical simulation of gap tidal current in Huaneng Caofeidian coal terminal

自曹妃甸建设以来,抛石堤因施工简单、施工速度较快、适应能力强、施工方法成熟、安全性能高等优点而被普遍采用。然抛石堤施工,不可避免要形成龙口,尤其在外海,四周无掩护的情况下,受海域自然条件影响,龙口合龙的施工一直是施工的难点。在华能曹妃甸煤码头项目抛石堤施工中,通过数学模型模拟施工期间可能存在的水流变换过程,为龙口合龙时间的选择、施工方案的设置提供依据,以确保龙口施工过程中抛石的稳定。

The ripped-rock embankment is extensively used in construction of Caofeidian because of its simple construction, rapid construction, good adaptability, mature construction method, and high safety performance. However, gap is formed inevitably in the ripped-rock embankment construction, especially in the sea, all around without cover, and gap closure construction affected by the marine natural conditions has always been a difficulty. During construction of Huaneng Caofeidian coal terminal project, we simulate the possible current change process by mathematical model to provide reference for the choice of gap closure time and the setting of construction plan and thus ensure the stability of gap closure riprap in the process of construction.
