强浪条件下半掩护港区波浪场数值模拟

摘要

以以色列南部新建Ashdod码头为工程背景，在分析港区自然条件的基础上，利用二维河口与海岸模拟软件MIKE21，建立了基础方案各个施工阶段港内泊稳模型。通过对不同施工阶段下半掩护港区波浪场进行数值模拟分析，掌握了港内波浪场的分布情况，确定港内正常施工时防波堤口门处的容许波浪要素。根据防波堤口门处的波浪统计资料，得到港区不同区域的最大作业波高标准以及港区不同区域不同施工阶段下全年不可作业的天数。研究结果为工期的合理安排和作业窗口的确定提供依据，并提出了科学合理的施工工序建议。%Based on the analysis of natural conditions and boundaries,numerical model of wave field of each construction phase was set up using MIKE21 wave stimulation model on the background of Ashdod port project.The wave propagation within the harbor was obtained by numerical analysis under different construction stages along with the results of the maximum working wave heights and unavailable working days.Reasonable schedule of construction was made and working window was selected according to the results.Moreover,this paper provides a scientific and reasonable construction procedure for the Ashdod port project.
