Numerical Simulation of Blasting Vibration Effect on Stability of High-lsteep Slope

It is important to explore the dynamic influence of blasting vibration on slope for the production safety in high steep slope blasting engineering.Related researches show that the FLAC3D can be used for dynamic response analysis of the slope,then a 3D model of Ahai power station′s high-steep slope was built by the software FLAC3D.By inputting the measured vibration data from the slope bottom,the stress field distributions,displacement field and velocity field in the slope were analyzed,which helps to disclose the effect of blast loading on slope stability.
