波浪作用下混凝土联锁排稳定厚度

通过水槽试验测定混凝土联锁排的波浪动水压力,并选择椭圆余弦波理论进行计算模拟。根据混凝土联锁排的受力分析,建立动力平衡方程,推导出波浪作用下的稳定厚度计算公式,探讨了波高、水深及波周期对混凝土联锁排厚度的影响。经过与其它公式及试验结果比较,证明所推导公式的合理可信。

Thickness of Concrete Slab Interlocking Mattress under Action of Waves

In order to analyze the needed thickness of the mattress under the action of waves,flume experiments were carried out.In the experiments,dynamic hydraulic pressure on both upside and underside of the mattress were measured,and its stability was observed.Analysis on the experimental results indicates that the dynamic pressure on the mattress accords with the cnoidal wave theory well.Based on the theoretic analysis,an expression to calculate the thickness of the concrete slab interlocking mattress under the action of waves is proposed,which is mainly determined by wave height H,water depth h and wave period T.The results obtained from the proposed formula were compared with those from other formulas and from the experiment.It can be concluded that the proposed formula in this paper can give reasonable thickness of a concrete slab interlocking mattress.
