摘要
在圆筒形防波堤和V形防波堤的基础上,结合离岸堤后形成V形和半圆形连续出现的韵律海岸的地貌平面形态特点,提出一种前墙为连续的半圆筒形防波堤形式。通过在波浪水槽内进行规则波物理模型试验,探究这一新型防波堤的波压力分布规律及波高、周期、水深等因素对波压力的影响。将试验结果与海港水文公式和合田良实公式计算的理论值对比分析,给出了以合田良实公式的折减系数来拟合新型弧形防波堤波浪总水平力的计算公式。结果表明:新型弧形防波堤上的波压力随波高、周期的增大而增大,其水平波浪总力比同等尺度直墙少10%左右。
Based on the circular cylinder breakwater and the V-shaped breakwater, considering the coastal geomorphic plane morphology characteristics that consecutive V-shape and semi circular coast would be formed behind the offshore breakwater,a form of breakwater is proposed with a semi-cylindrical continuous front wall. Through the regular wave model experiment in a wave flume,the wave force distribution and the influence factors for wave forces on this new breakwater are studied,such as wave height,period,water depth,etc. The results are compared with theoretical values according to the Seaport hydrology standard formula and the Goda formula,and the modified Goda is given for total horizontal wave force on this new breakwater. The results show that the wave pressure on curved breakwater increases with the incease of wave height and wave period,and that the total horizontal wave forceis less than that of the same scale vertical breakwater by about 10%.
