摘要： Wave-induced harbour resonance is numerically investigated inside a harbour with lateral cavities. The theoretical solutions for the amplification parameter are compared with the simulated results under varying dimensionless wave numbers in order to verify the simulation model in a rectangular harbour at a constant depth. The results indicate that the numerical model can correctly calculate the natural frequency and the natural wave height. A range of calculations are performed for harbour resonance with one pair of lateral cavities, two pairs of lateral cavities and three pairs of lateral cavities, respectively. The simulated results indicate that the amplitude of the amplification parameter decreases both at the primary natural oscillation and the secondary natural oscillation, as the number of lateral cavities increases. The dimensionless wave number reduces as the number of lateral cavities increases both at the primary natural oscillation and the secondary natural oscillation as well.
