摘要
针对港池和航道平面尺度的分析和计算,PIANC规范提出在概念设计阶段根据自然条件、船舶的基本参数、周边泊位的影响,利用公式对水域尺度进行快速计算,在详细设计阶段应采用仿真试验模拟实际工况,准确地确定航道布置及尺度。以东南亚某LNG码头工程为例,将采用PIANC规范公式与仿真试验计算的港口水域尺度进行对比。结果表明,与公式计算相比,仿真试验能更准确、真实地模拟不同工况下的船舶航行轨迹。成果可为类似工程提供借鉴。
In view of the analysis and calculation of the water layout dimensions of harbor basin and channel,the PIANC specification proposes that in the conceptual design stage,the water layout dimension should be calculated rapidly by using formulas according to the natural condition,the basic parameter of ship and the influence of surrounding berth.In the detailed design stage,the simulation test should be used to simulate the actual working condition and accurately determine the channel layout and dimension.Taking the LNG terminal project in Southeast Asia as an example,this paper compares the formula of PIANC specification with the calculation of water layout dimension by simulation test.The results show that the simulation test can simulate the ship’s trajectory under different working conditions more accurately and truly than the formula calculation.The achievements can provide references for the similar projects.
