Centralized resonant seismic metamaterial for attenuating low frequency surface acoustic waves
The invention relates to the technical field of seismic propagation control, in particular to a centralized resonance seismic metamaterial for attenuating low-frequency surface acoustic waves. Comprising a plurality of integrated resonators which are arranged periodically, and each integrated resonator comprises a concrete platform which is in a hexahedron shape, the top surface and the bottom surface of the concrete platform are square, and the bottom surface of the concrete platform is fixedly connected with the ground; the steel thin-wall hollow square pipes are vertically and fixedly arranged on the inner sides of the middles of the side edges of the top surface of the concrete platform respectively, and the bottoms of the steel thin-wall hollow square pipes are arranged in insertion holes in the top surface of the concrete platform; the inserting holes are filled with the rubber wrapping layers, and fixed connection between the steel thin-wall hollow square pipe and the concrete platform is achieved. The subwavelength seismic metamaterial is small in size and low in cost, and attenuation of the subwavelength seismic metamaterial on low-frequency seismic surface waves is effectively achieved.
本发明涉及控制地震传播技术领域，特别是一种用于衰减低频弹性表面波的集化谐振地震超材料。包括数个周期性排列的集化谐振器，集化谐振器包括：混凝土平台，呈六面体状，其顶面和底面均为正方形，其底面与地面固定连接；数根钢制薄壁空心方管，分别垂直固定设置在混凝土平台顶部表面的各侧边中部的内侧，其底部设置在混凝土平台顶部表面的插孔内；橡胶包裹层，填充在插孔内，实现钢制薄壁空心方管和混凝土平台之间的固定连接。其尺寸小、成本低，有效实现了亚波长地震超材料对低频地震表面波的衰减。
