摘要

我们概述了自大规模实验[S.Brûlé,Phys.Rev.Lett.112133901(2014)]以来,在控制薄板和厚板中的弹性波方面取得的一些最新研究进展,该实验证明了地表地震波与在米尺度上构造沉积土的孔之间的显著相互作用。我们进一步研究了建筑物结构土壤中压缩体波的地震波轨迹。作为基础的夹杂物对土壤的显著替代,提出了这些结构性土壤有效动力特性的问题。在土壤和建筑物都具有完美弹性条件的情况下,建筑物会相互作用并强烈影响弹性体波;在[Guéguen et al.,Bull.Setroml.Soc.Am.92794-811(2002)]中指出了这种场地与城市的地震相互作用,我们研究了各种场景,以说明可能的各种行为。

The influence of building interactions on seismic and elastic body waves
We outline some recent research advances on the control of elastic waves in thin and thick plates, that have occurred since the large scale experiment [S. Brûlé, Phys. Rev. Lett. 112, 133901 (2014)] that demonstrated significant interaction of surface seismic waves with holes structuring sedimentary soils at the meter scale. We further investigate the seismic wave trajectories of compressional body waves in soils structured with buildings. A significant substitution of soils by inclusions, acting as foundations, raises the question of the effective dynamic properties of these structured soils. Buildings, in the case of perfect elastic conditions for both soil and buildings, are shown to interact and strongly influence elastic body waves; such site-city seismic interactions were pointed out in [Guéguen et al., Bull. Seismol. Soc. Am. 92, 794–811 (2002)], and we investigate a variety of scenarios to illustrate the variety of behaviours possible.
