摘　　要：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.The velocity and quantity of waves of primary phase Rayleigh-wave of rock type slopes to slip were calculated systematically. The feature of Rayleigh-wave primary frequency dispersion of rock type slopes and the evolution law of Rayleigh-wave frequency dispersion of slope from steady state to unsteady state were also concluded. Then,the phase velocity, wave number and frequency dispersion curve feature of Rayleigh-wave in the process of slope to slip were extracted. All these lead the method of Rayleigh-wave not only be used to detect the slip plane or structural plane of unsteady slope, but also to evaluate slope＇s stability and to forecast the situation of slope to slip. 2figs., 1tab., 12refs.
