摘要
为探索海洋中陡变地形对地坪上波浪传递的影响,采用二维波浪物理模型试验,从地形边坡这一因素入手,进行了一系列研究,观测了地坪上波高、周期、增水等参数的变化。通过对实测数据进行分析,初步明确了陡变地形边坡变化对波浪传递的影响特点,即在试验所采用的1∶0.6~1∶10地形边坡范围内,相同波浪作用下,随着坡度逐渐变缓,地坪上波高、周期、增水等明显减小。试验研究成果为了解及开发利用这种特殊的地形地貌提供借鉴参考。
In order to explore the influence of steep slope on the wave transmission on the ground,from the aspects of topography and slop,we carried out a series of studies by2D physical model test,observed some data change of wave height,wave period and wave set-up,etc.Through the analysis of the measured data,we initially confirmed the influence of the change of steep slope on wave transmission.The wave height and water set-up gradually decrease with the slope gradient,and change linearly,in the range of1颐0.6to1颐10terrain slope used in the experiment,under the same wave action.The research results can provide references for the understanding and development of this special topography.
