摘要
针对新型组合式密排桩基防波堤的透浪特性问题,基于现有密排桩基防波堤研究成果,通过物理模型试验,开展此新型结构透浪特性的多因素分析研究,并在试验结果的基础上,拟合出组合式密排桩基防波堤透浪系数的计算公式.结果表明,增设桩间肋板和桩后插板等组合式措施对减少透浪系数均有影响,其中增设桩间肋板对于相对桩间距小的密排桩基结构效果甚为明显.
Abstract
To analyze the wave transmission characteristics of combined closed-pile breakwater,we carry out physical model test to take the multi-factor analysis on wave transmission characteristics of the new structure based on the relevant existing research.On the basis of model test results,we obtain the fitting formula of wave transmission coefficient on the breakwater with the combined closed-pile foundation.The results show that measures of adding inter-pile rib plate and post-pile panel have remarkable effect on reducing the wave transmission coefficient,especially that the inter-pile rib plate can obviously reduce the wave transmission coefficient of the breakwater with closed-pile foundation with small relative pile spacing.
