摘　　要：排水龙口是大型围海造陆工程施工过程中一个重要结构,其设计合理与否对工程吹填施工至关重要。针对地中海区域受波浪影响严重的某大型围海造陆工程,采用有限元法,分析了6种工况下波浪场情况,得到了每种工况下波高分布规律及其对龙口位置选择影响特性,同时结合现场施工组织情况,确定了最优龙口位置;设计了排水龙口结构,验算了其稳定性;开展了龙口局部冲刷验算,在确定存在较大冲刷风险情况下,提出了冲刷防护方案,可为类似工程提供参考。Drainage closure gap is an important structure in the construction of large-scale sea reclamation projects,thus its reasonable design plays a key role in dredger-filling work.Based on a large-scale sea reclamation project in the Mediterranean region,which is seriously affected by waves,a finite element method was used to analyze the situation of wave field under 6 working conditions,which produced the law of wave height distribution and the related influence on the selection of closure gap location.And then the optimum location was determined by referring to the field construction organization.The structure of drainage closure gap was designed and verified from the aspect of stability.Furthermore,a local scouring calculation of the closure gap was carried out,and a scour shielding proposal was proposed subject to higher risk of scour,which could provide a reference for similar projects.
