Breakwater for reducing long-period waves based on water wave resonance principle
The invention relates to the technical field of coast engineering, and discloses a breakwater for reducing long-period waves based on a water wave resonance principle, the breakwater comprises a C-shaped resonator and a plurality of pile legs, a base is connected between the C-shaped resonator and the plurality of pile legs, the C-shaped resonator is detachably connected with the upper end of the base through a bolt, and the C-shaped resonator is detachably connected with the lower end of the base through a bolt. The multiple pile legs are circumferentially distributed at the lower end of the base, the base, the C-shaped resonators and the multiple pile legs jointly form a wave absorbing unit, the wave absorbing units are arranged in a rectangular array to form the breakwater, the outer diameters, the inner diameters and the opening sizes of every two adjacent C-shaped resonators in the array gradually change according to a certain rule, and the C-shaped resonators are of a structure with large cavities and small openings. The method comprises the following steps of: inducing resonance to subtract a long wave which is several times of the wavelength of a cylindrical characteristic size, enabling waves with different frequencies to generate local resonance wave absorption at different spatial positions of the array type breakwater, effectively subducting long-period waves in a wide-frequency domain range, and forming a sheltering water area which is stable in operation behind the breakwater.
本发明涉及海岸工程技术领域，且公开了一种基于水波共振原理的消减长周期波浪防波堤，包括C形共振器和多个桩腿，C形共振器和多个桩腿之间共同连接有基座，C形共振器通过螺栓与基座的上端可拆卸连接，多个桩腿周向分布在基座的下端，基座、C形共振器和多个桩腿共同组成一个消波单元，消波单元按矩形阵列排布组成防波堤，且阵列中相邻的两个C形共振器的外径、内径以及开口大小按一定规律进行渐变，C形共振器利用大腔体小开口的构造，诱发共振消减数倍于圆柱特征尺寸波长的长波，使不同频率的波浪在阵列式防波堤的不同空间位置处发生局部共振消波，宽频域范围内长周期波浪均被有效消减，在防波堤后形成作业泊稳的掩蔽水域。
