| Abstract: | Based on the principle of dynamical response time history analysis,taking a practical engineering as example,the simulation with the dynamic FEM was used to analyze the disturbance effect of blasting vibration on rock slope,the characteristics of acceleration response,displacement response and stress response in different parts of rock slope.The results showed that the vibration velocity,displacement value and stress value of slope obtained by means of time-history analysis can reflect more objectively and truly the dynamic response results of slope in blasting vibration and the disturbance effect of blasting. |
