| Abstract: | Taking the cutting excavation of Beijing-Qinhuangdao freeway slope as an example, the dynamic features and the distribution regularity of blasting vibration waves such as stress field, displacement field and velocity field were analyzed and the influence of blasting vibration on the mountainous freeway-cutting slope was studied by numerical simulation. The comparison of simulation results with in-situ measuring results shows that they are approximate. |
