摘要

我们建议使用埋在敏感位置周围的共振结构阵列作为对地表地震波的保护。共振结构由混凝土管组成，其中包含由软轴承悬挂的钢体。我们在数字和规模实验活动中验证了他们的设计。该阵列在[1-10Hz]频率范围内衰减和重定向瑞利波。

Seismic surface waves attenuation by buried resonators

We propose to use arrays of resonant structures buried around sensitive locations as protection against surface seismic waves. The resonant structures consist of concrete tubes containing a steel mass suspended by soft bearings. We verify their design numerically and on a scaled experimental campaign. The arrays attenuate and redirect Rayleigh waves within the [1-10Hz] frequency range.
