淹没状态下半圆型防波堤的水力特性研究
Hydraulic experimental study on submerge semi-circular breakwaters
-
摘要: 以淹没状态下的半圆型防波堤为研究对象,采用不规则波断面模型试验,结合典型实例分析了堤体波压分布的特点,指出波浪经过堤顶破碎与否直接影响到堤体所受波力的大小,并建议了开孔办法和波力计算方法.Abstract: In the light of typical cases,the distribution characteristics of the wave forces exerted on semi-circular breakw aters by irregular waves are studied.It is pointed out that whether the waves going through the top of the breakwater are broken or not will produce a great impact on wave force value.Furthermore,the reasonable holing methods and the formulae to calculate the design wave forces are also proposed.
