摘　　要：为增大双层板式防波堤的波能耗散和防波堤结构的稳定,提出了的一种新型桩基双层板式防波堤,通过物理模型试验,对比分析了该防波堤结构(模型c)与另两种结构型式的防波堤(模型a、b)在不同的波浪参数下透射系数、反射系数的变化关系,探讨了新型桩基双层板式防波堤(模型c)透射系数、反射系数随相对波高、相对水深及相对淹没深度的变化关系,分析了其波能损耗情况。结果表明,在试验范围内,对于长周期波,模型c比其他两种型式的防波堤消波效果好;当水深与模型顶平齐时新结构(模型c)对波能的消耗大于淹没和出水两种情况,说明防波堤高程与水位平齐时其消波效果较好。A new type of pile foundation double horizontal plate breakwater （model c） is presented to in-crease wave energy dissipation and stability of the double-plate breakwater. Based on the physical model experiments, the relationship between the breakwater transmission coefficient and reflection coefficient with relative plate width was obtained and compared with other two kinds of breakwaters （models a and b）. It discussed the transmission coefficient and reflection coefficient of new breakwater change with relative wa-ter depth, relative wave steepness, relative submerged depth, and the wave energy dissipation of new break-water was also analyzed. The results show that the new breakwater has good effect on wave absorption for the long period wave in the experimental parameters and the wave energy dissipation is better when the new breakwater elevation as the same with the water level than other elevations.
