Research on Dynamic Response of Rock Single-free-surface Slope under Explosion Based on Flac2D

LIU Lei,XIE Zuo-qiang (School of Civil Engineering and Architecture,Wuhan University of Technology,Wuhan 430070,China)  
Based on flac2D,a numerical model of rock single-free-surface slope under explosion is established.And some problems found during the procedure of modeling are discussed,which reveals that the frequency of vibration becomes lower with the increase of the slope height.Peak particle velocity is applied as the judgment standard of slope dynamic response.Then through changing the height and obliquity of the slope,some results are obtained,which confirms that,under dynamic loading,slopes will not only appear magnifying effect,but also with the increase of slope,the velocity first increases and then decreases and the peek velocity increases if the obliquity is constant.
