波浪作用下混凝土联锁排稳定厚度研究

In order to analyze the needed thickness of the mattress under the action of wave, flume experiments were carried out. In the test, dynamic hydraulic pressure on both upside and underside of the mattress were measured, and the stability of it was observed. Analysis on experimental results indicates that the dynamic pressure on the mattress accords with the cnoidal wave theory well. Based on the theoretic analysis, the expression of the thickness of the concrete slab mattress under the action of wave 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 the concrete slab mattress.
