T型防波堤水平板波浪冲击压强试验研究

通过规则波与T型防波堤相互作用的试验研究,揭示了T型防波堤底部所受冲击压强产生的原因。分析波浪冲击压强历时曲线、相对板宽对冲击压强沿水平板底部分布的影响,得到T型防波堤水平板冲击压强的特性以及2大影响因素:相对超高和波陡。应用因次分析的方法,推导出T型防波堤底板最大相对冲击压强计算的经验公式。结果表明,该公式计算结果与试验值吻合较好,有一定的适用性。

Experimental study on impact pressure of waves on a horizontal plate of T-type breakwaters

Through experimental study on the regular wave interaction with the T-type breakwater,the causes of the impact pressure effecting at the bottom of T-type breakwater were revealed.By analyzing the wave impact pressure duration curve and the influence of the relative width on the impact pressure distribution along horizontal plate at the bottom of T-type breakwater,the impact pressure characteristics along the horizontal plate of T-type breakwater and two main influencing factors including relative wave height and wave steepness were observed.Adopting the dimensional analysis method,the empirical formula of maximum relative impact press of T-type breakwater was deduced.The results show that the calculated results are in good agreement with the experimental value,and the formula has specific applicability.
