Title: DYNAMIC STABILITY ANALYSIS FOR EXCAVATION BLASTING OF HIGH SLOPE OF JINPING-1 HYDROPOWER STATION
Abstract: With the introduction of time history analysis method to ratio method of shearing strength of rock,the stability factor of the potential slide mass was achieved under the effect of blasting vibration load by analyzing the whole blasting vibration process at a certain time step.High slope excavation blasting at the left bank over EL.1885m of Jinping-I Hydropower station was evaluated by using ratio method of shearing strength about dynamic stability,which well reflected the variation process of the slope stability during excavation blasting,and provided a reference for the optimization of blasting parameters,guidance of vibration reducing measures and slope retaining.The results were very significant for analyzing similar highslope excavation blasting work in the future.
