【摘要】：码头前沿水域的横流过大容易导致船舶撞击码头或系船缆绳断裂,进而引发安全事故,因此研究码头前沿水域的流场状况对码头轴线合理选取和船舶的安全靠泊有着非常重要的意义。基于桩群概化方法,采用Mike21软件中的三角形网格水动力模块(FM模块)对曹妃甸矿石一期、矿石三期高桩码头附近的流场进行了数值模拟,并与现场实测流速、流向进行对比验证,确定了模型中的桩群影响参数。在此基础上,深入研究相邻高桩码头桩群阻力对周边海域的影响,并对码头前横流进行计算和分析。此方法实施简单、计算效率高,对大范围海域影响研究结果合理,对高桩码头前沿水域有关流速、流向的计算结果更加准确,对码头轴线合理选取和船舶安全靠泊有重要的参考意义。
[Abstract]:The excessive cross flow in the front waters of the wharf can easily lead to the ship striking the wharf or breaking of the mooring cable, thus causing a safety accident. Therefore, it is of great significance to study the flow field in the wharf forward waters for the reasonable selection of the wharf axis and the safe berthing of the ship. Based on the method of pile group generalization, the flow field of Caofeidian ore in the first stage and the third stage of high pile wharf is numerically simulated by using triangular grid hydrodynamic module (FM module) in Mike21 software, and the flow field is compared with the field measured velocity. The influence parameters of pile group in the model are determined by comparing and verifying the flow direction. On this basis, the influence of pile group resistance of adjacent high pile wharf on the surrounding sea area is studied, and the cross flow in front of the wharf is calculated and analyzed. The method is simple and efficient, and the results of the study on the influence on large sea area are reasonable, and the calculation results of the velocity and direction of the flow in the front waters of the high pile wharf are more accurate. It has important reference significance for the reasonable selection of the wharf axis and the safe berthing of the ship.
