摘要

采用基于时域粘弹性人工边界的Rayleigh波输入方法,进行了土-地下结构相互作用体系在Rayleigh波作用下的动力时程反应分析,对Rayleigh波作用下地下结构的地震反应特性进行研究。重点讨论了地下结构材料强度、结构厚度以及土层刚度等因素对Rayleigh波作用下地下结构地震反应的影响。结果表明Rayleigh波对浅埋地下结构的地震动力反应影响显著,将使结构产生较大的内力与变形,在地下结构抗震设计尤其是浅埋地下结构的抗震设计时应予以足够的重视。

Abstract

Dynamic time history analysis of soil-structure system during propagation Rayleigh waves is carried out using the Rayleigh wave input method based on viscous-spring artificial boundary, and the seismic response of a underground structure during propagation of Rayleigh wave is studied. The influences of structure material strength, structure thickness and soil stiffness are investigated in detail. Numerical analysis results show large effect of Rayleigh wave on the dynamic response of shallow underground structures. The internal force and deformation cause by Rayleigh wave are significant, and the influences must be taken into account in seismic design of underground structures.
