摘要:
采用两种假定的层状土介质模型,通过快速标量法和薄层刚度法分别计算Rayleigh波的频散曲线,包括两层介质和三层介质两种地基土模型,分析对比了层状介质土Rayleigh波的频散特性,发现在低频阶段薄层刚度法计算效果优于快速标量法,在高频区域二者差别不大。
Abstract:
We mainly calculated the Rayleigh wave frequency dispersion curve of multilayered soil respectively,including two-layered and three-layered soil model,adopting thin-layer method and rapid scalar method.In addition,we have analyzed Rayleigh wave disperse property of multilayered media soil.It is found that thin layer method is superior to rapid scalar method in low frequency domain,while it has little difference between each other in high frequency domain.
