| 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. |
