根据边坡失稳的地球物理模型,系统研究了岩石边坡失稳的瑞利面波基阶模的相速度、波数响应特征,总结了边坡从稳定→失稳演化过程的瑞利面波基阶模频散特征变化规律,从中提取边坡失稳的瑞利面波基阶模相速度、波数、频散曲线等特征标志,使瑞利面波法不仅能用于探测边坡失稳的滑动面或结构面,而且还能评价边坡的稳定性,对边坡失稳进行综合预测预报. According to the geophysical model of slope instability, the phase velocity and wave number response characteristics of the unstable Rayleigh-surface wave-order mode of rock slope are systematically studied. The Rayleigh surface wave Based on the regularity of fundamental-mode dispersion characteristics, the characteristic signs such as phase velocity, wavenumber and dispersion curve of Rayleigh surface wave instability are extracted, so that Rayleigh surface wave method can not only be used to detect slope instability Of the sliding surface or the structure of the surface, but also evaluate the stability of the slope, the slope of a comprehensive forecast of instability.
