摘要
通过二维水槽内规则波以及不规则波作用下开孔沉箱的受力试验研究,分析研究了明基床上开孔沉箱所受的总力矩与相对基床高度、消浪室相对宽度、相对水深、波陡以及开孔率等影响因素间的相关关系,并利用最小二乘法给出总力矩比值(开孔沉箱/实体沉箱)与其影响因素间的拟合公式,同时将计算值与试验值对比,二者吻合较好,所得经验关系式可供工程设计参考。
Based on the experiments of regular wave and irregular wave with perforated caisson in the 2-d wave flume, this paper dis- cusses the relationship between the total moments of perforated caissons and the major influencing parameters, such as the relative foun- dation height, the relative chamber width, the relative water depth, the wave steepness and the porosity of perforated wall. The empiri- cal formulae for the calculation of the ratios of total moment perforated to block caisson and their major factors are proposed by using the least square method. Predicted values are compared with the measured results. It can be seen that these simplified formulae work well and can be applied in the practical engineering.
