摘要

通过对316国道土质边坡及岩质边坡进行振动响应测试，研究交通荷载引起土质及岩质边坡振动加速度大小及其空间变化特征，同时利用FFT方法对振动信号进行频谱分析，得到岩质及土质边坡的振动响应频谱特性。测试及分析结果表明，振动波传播过程中携带了反映介质固有特性的信息，岩质及土质边坡对交通荷载的响应均较为敏感，相同荷载在土质边坡引起的振动加速度及振动幅值大于岩质边坡，其中土质边坡沿坡由下向上振动响应有减弱的趋势，且振动在短距离内衰减较快，而岩质边坡振动响应在短距离内衰减较慢；主频随着振动波的衰减有向低频移动的趋势。测试为分析振动传播途径和研究振动对边坡稳定性的影响提供了宝贵资料，对多因素引起的边坡稳定性评价有重要的实际意义。

Abstract

By mean of the vibration testing measurement

accelerator of vibration and its spacial varied features of the soil and rock slope located in 316 State Road due to the traffic loads were analyzed; moreover the vibration wave signals were analyzed by FFT; and frequency spectrum characteristics of vibration wave were obtained. The results show the information reflected inherent characteristics it carried during vibration wave propagation. The vibration response of soil and rock slope is equivalent sensitive due to traffic loads; the accelerator and amplitude of vibration of the soil slope is greater than that of rock slope under same loads. The vibration response of the soil slope is decreases little by little from up to down along the slope and its attenuation is compared fast in short distant; but the vibration attenuation of the rock slope is compared slow in short distant. Main frequency moves to low frequency with vibration wave transmitting. The testing result will offer reference for analyzing propagated pathway of vibration and its influence on the stability of slope. Furthermore it is of practical meaning to the evaluation of slope stability caused multifarious factors.
