| 摘 要： | 土层剪切波速结构是工程场地条件的重要的基本参数，许多研究者关注利用从地脉动台阵中推得的Rayleigh波或Love波的相速度频散曲线反演实际工程场地剪切波速度结构。探讨从地脉动台阵观测的记录中提取Love波相速度的频散曲线的方法，从厦门某工程场地的地脉动台阵观测三分量记录中提取了Love波相速度的频散曲线，将提取的结果与根据实际场地资料构成的水平成层介质模型计算的Love波相速度的频散曲线进行了对比，为下一步的反演奠定了基础。 |
| 关 键 词： | 地脉动台阵 Love波 Rayleigh波 频散曲线 |

| Abstract: | Shear wave velocity structure of soil layers is the primary parameter of site condition. Dispersive curve of phase velocity of surface wave, Rayleigh wave or Love wave inferred from microtremors array has been emphasized by many researchers. In this paper, the Love wave dispersion curve is derived from three component records at microtremors arrays and applied to a practical site in Xiamen. The acquired dispersive curve of Love wave was compaced with that calculated from the horizontal layered model constructed by downhole measurement data. |
| Keywords: | microtremors arrays Love wave Rayleigh wave dispersive curve |
