爆破震动频率对边坡稳定性的影响
Effect of blasting vibration frequency on slope stability
摘要
Abstract
A slope finite element model with the blasting seismic waves was set up. Using modal analysis and harmonic response analysis, the natural frequency of the slope was obtained. The slope dynamic response at different blasting frequencies was obtained through transient dynamics analysis. Finally, the reasonable blasting frequency was forecasted for the slope. The results show that by adjusting the blasting scale and choosing appropriate blasting frequency to avoid producing resonance with the slope, the stability of the slope can be improved.关键词
