中文摘要：
通过水槽内规则波以及不规则波作用下明基床上开孔沉箱的稳定性试验,分析研究了三种基床高度上开孔沉箱的稳定性与相对基床高度、消浪室相对宽度、相对水深、波陡以及开孔率等因素间的相关关系,并利用最小二乘法给出开孔沉箱最小自重与其影响因素间的拟合公式,同时将计算值与试验值进行比较,二者吻合较好,试验结果可供工程设计参考应用。
英文摘要：
Through 2-D experiments in the wave-current flume under the condition of regular waves and irregular waves, an experimental investigation has been carried out on the stability of a perforated caisson sitting on the rubble mound foundation. This paper discusses the relationships between three heights of the foundation and main influence factors,such as the relative foundation height,the relative chamber width,the relative depth,the wave steepness,and the porosity of perforated caisson,have been analyzed.A formula is given of the relationship between the minimum weight of perforated caisson and the main influence factors using the least square method（ LSM）. In addition,comparison of the calculated value with the experimental value shows the consistence of the two values. So the formula can be applied in practical engineering design and application.
