Ultrathin seismic volume wave seismic metamaterial using site expansion lattice
The invention discloses an ultrathin seismic wave body wave seismic metamaterial using a site to fill crystal lattices, which comprises a plurality of groups of seismic metamaterial units which are sequentially arranged below the earth surface at equal intervals from inside to outside by taking a target site as a center, the seismic metamaterial unit comprises a horizontal combined steel plate arranged at the bottom of the target site and a vertical combined steel plate vertically arranged on the periphery of the bottom of the target site, the vertical combined steel plate and the horizontal combined steel plate are closed and enclosed, and the combined steel plate comprises a middle steel plate layer and rubber layers arranged on the two surfaces of the middle steel plate layer; according to the scheme, the seismic metamaterials are arranged around the target site at equal intervals, the intervals are equivalent to introduction of soil layers with the same thickness, lattice constants of one-dimensional local resonance photonic crystals can be equivalently expanded, a plurality of low-frequency broadband gaps are formed in any fluctuation mode, and the low-frequency broadband bandwidth is improved. And the closed enclosure arrangement mode can reflect incident seismic waves in any direction, so that the whole target site is prevented from being influenced by the seismic waves.
本发明公开了一种使用场地填充晶格的超薄地震波体波地震超材料，包括以目标场地为中心，从内至外依次等间距设置在地表以下的多组地震超材料单元，地震超材料单元包括设置在目标场地底部的水平组合钢板以及竖直设置在目标场地底部外围的竖直组合钢板，竖直组合钢板和水平组合钢板封闭围合，组合钢板包括中间钢板层以及设置在其两表面的橡胶层；本方案地震超材料等间距地布置在目标场地四周，该间距相当于引入同等厚度的土层，能够等效的扩充一维局域共振声子晶体的晶格常数，在任意波动模式下形成多条低频宽带宽带隙，且封闭围合的安置方式能够反射任意方向入射的地震波体波，使得整个目标场地免受地震波体波影响。
