Flume experiments were performed to investigate the needed thickness of concrete mattress under wave action. Hydrodynamic pressures above and below the mattress were measured, and the mattress's stability was observed. Results indicate that the hydrodynamic wave pressure on the mattress accords well with cnoidal wave theory. Based on the theoretical analysis, an expression of the required thickness of a concrete mattress under wave action is proposed, which is mainly determined by wave height H, water depth h and wave period T. The theoretical coefficient of the semi-empirical formula was also predigested, according to the theoretical analysis.
