【摘要】 通过斜向不规则波对半圆形防波堤(不开孔出水堤)作用的试验研究,考虑波陡 Hs／Ls,相对波高Hs／d,波浪入射角θ等主要影响因素,给出了单位堤长所受水平波浪力Ph、竖向波浪力Pv和波浪浮托力Pu随上述影响因素的变化,且着重分析了负向水平波浪力Ph- 大于正向水平波浪Ph+出现的条件。更多还原

【Abstract】 Based on diagonal irregular wave physical model test, the hydraulic characteristics of the Semi-circular Breakwater are studied in this paper. The variation of wave forces including the horizontal wave force, the total uplift pressure and the uplift pressure applied to the bottom slab on unit length of semi-circular breakwater along with the main effective factors are analyzed. Especially sometimes the troughs of horizontal wave force rather than wave crests lead to the disruption of the breakwater.更多还原
