【摘要】 以近30aWRF再分析风场作为驱动,利用SWAN数值模式对中石化广西液化天然气(LNG)项目海域的灾害性海浪特征参数进行数值模拟,并与设计波浪要素进行对比。通过模拟结果与T/P高度计波浪资料、浮标及海洋站观测资料的对比验证,表明波浪模拟结果较好。项目外海海域有效波高极值集中在E～SE向,强浪向为SE(SSE)向。项目工程本身主要受到SSE、S和SSW向波浪的影响,其中S向影响最大。项目海域100a一遇极端高潮位和设计高潮位下SSE向波高的评估值均大于设计值,除极端高潮位下有效波高外SW向的评估值与设计值相当,其他方向波高的评估值低于设计值。更多还原

【Abstract】 Driven by the recent 30 reanalysis wind field, the characteristic parameters of disastrous wave in Sinopec Guangxi liquefied natural gas(LNG) project were calculated by the SWAN numerical model and compared with the designed values. The simulation results were fairly well in comparison validation of the T/P altimeter, the buoy, and the ocean station wave data. Extreme values of effective wave heights were mainly located at the east～southeast direction, and the strong wave direction was in the southeast(south-south-east) in the LNG project open sea. The LNG project itself was mainly affected by wave direction in the south-south-east, the south and the south-south-west, and the most drastic wave was in south direction. In the LNG project surrounding waters, evaluation results of wave height at 100 a return period extreme and designed tidal levels in the south-south-east direction were greater than the designed values. The evaluation results and designed values in the southwest direction were fairly equivalence, and the evaluation results were lower than the designed values in other directions.更多还原
