摘　　要：为更好的评估海啸波作用于斜坡堤的爬高,通过在无反射造波机水槽中造孤立波模拟海啸与斜坡堤作用。分析了海啸波沿斜坡堤的最大爬高,得到了扭王字块、栅栏板和大块石3种护面结构,1∶1.5和1∶2两种坡度下的试验数据。与有关学者提出的经验公式进行了比较,并考虑坡面不同护面的糙率影响,提出了新的爬高公式。成果表明,新提出的爬高经验公式与大量的实测数据相关性很好。In order to evaluate the impact of tsunami wave climbing along the sloping breakwater, the solitary wave was produced in the absorbing wave maker tank to simulation the interaction between the tsunami and the slop breakwater. The maximum tsunami wave run-up height was analyzed, the experimental data of three kinds of protective structures, i.e. the accropode armour, the barrier board and the stone at slope 1:1.5 and 1:2 were obtained. Compared with the empirical formula with other relevant studies, and considering the influence of roughness of different armour, a new formula of the maximum tsunami run-up height along the sloping breakwater was proposed. The results show the good correlation between the new empirical formula and a large number of measured data.
