| Abstract: | According to the blasting excavation project of a cutting slope, the finite element model is used to carry out numerical simulation, and the propagation law of the stress field, displacement field and velocity field of the blasting vibration wave in the slope medium is analyzed. Combined with the blasting vibration monitoring, the influence of blasting excavation on the stability of cutting slope is analyzed. The analysis results can help to realize blasting construction safety and maintain slope stability. |
