摘要

将传统阻波块改进为具有相同厚度的复合多层阻波块(以三层阻波块为例)。首先，建立了非饱和地基中复合多层WIB的物理模型，并基于波动理论研究了非饱和多孔弹性介质中复合多层WIB对S波的隔震效应。本研究的目的是提高WIB的隔离频率，并通过选择合适的波阻抗比来显示最佳的隔离效果。分析了饱和对隔振效果的影响。

Study on the isolation effect of a composite multilayer wave impeding block on the S-wave in an unsaturated foundation

The traditional wave impeding block (WIB) is improved to a composite multilayer WIB with the same thickness (tri-layer as an example). Firstly, a physical model of the composite multilayer WIB installed in an unsaturated foundation is established, and the isolation eﬀect on the S -wave is studied based on the wave theory in unsaturated porous and elastic media. The purpose of this study is to enhance the isolation frequency of WIB and to show the best isolation eﬀect achieved by selecting the appropriate wave impedance ratio. The inﬂuence of saturation on its vibration isolation eﬀect is also analyzed.
