摘　　要：在港口海岸工程中,防波堤的尺寸及平面布置对港内各处波高分布有着至关重要的影响。文章针对阳江闸坡一级渔港进行了波浪整体物理模型试验,利用82个波高传感器,测量了港区初步设计方案实施后设计高水位50 a一遇波浪重现期条件下的波高分布。结果表明,各向浪作用下已有内港池H 1%波高小于1 m的锚泊区面积可达61.4万m 2,内外港池H 1%波高小于1 m的锚泊区面积可达67.4万m 2,掩护水域面积满足一级渔港要求,但方案对偏北的浪向掩护效果相对较差。试验发现,南堤和西堤外的深槽地形引起波浪折射,对堤外波高分布产生较大影响。在此基础上,试验对规划方案进行了初步评估。在W向浪作用下,延长的防波堤有效地增加了外港池掩护面积,外港池内H 1%波高小于1 m的600 HP及以下渔船锚泊区面积比初步设计方案增加约4.6万m 2。试验结果为防波堤平面设计提供了科学依据。In port and coastal engineering,the size and layout of breakwater are vital to the wave height distribution in the harbor basin.In the present study,an integral physical model test on wave height distribution was carried out for the Zhapo fishery port in Yangjiang,and 82 wave height sensors were used to measure wave height distribution under the conditions of design high water level and waves with 50-year recurrence period after the implementation of the preliminary design scheme.The results show that the area of sheltered water with H 1%less than 1 m reaches 614000 m 2 in the inner harbor basin and 674000 m 2 in the whole harbor basin,which meets the requirement of first-grade fishery port,however,this scheme is slightly less effective in covering the northward wave direction.The deep trough outside the south and west breakwaters leads to wave refraction,which influence the wave height distribution in the harbor.Thus,the planning scheme was tested.Under the influence of waves in the W direction,the extended breakwater can effectively increase the sheltered area of the outer harbor basin,and the mooring area for fishing vessels of 600 HP and below with H 1%less than 1 m is increased by about 46000 m 2 compared with the preliminary design scheme.The model test provides scientific support for the plane design of breakwater.
