FLAC3D SIMULATION FOR DYNAMIC RESPONSE OF THE SLOPE UNDER EXPLOSION LOADING
Wang Jian-gu · Engineering Blasting · 2014
In order to research dynamic response rules under explosion loading of the western slope in Buzhaoba,a model of dynamic calculation and simulation had been established and a vibration wave had been imposed on the slope.The calculation results had been researched and discussed from three aspects including distribution of stress field,velocity field and displacement field by using software FLAC3D.The results showed that under the action of blasting loading,compressive stress of the slope increased gradually with the increasing of the slope depth,and the particle velocity and displacement of the slope presented amplification effect with increasing of the elevation.Dead weight stress was the main influence factor,and blasting loading had little effect on the slope.
