Experiment of the rockfall impact characteristic onto gravel cushion
Rockfall is one of common geological disasters in the mountainous area.The experiment gained the impact waves for cushion soil mass contained 12density,4 soil-rock ratio,4 cushion obliquity,3 moisture content,3 rockfall quality,5 height of rock fall.Used the wavelet theory to deal with the experiment waves,analyzed the experiment results:with rocks mass,the height and density increased,the impact force is increasing,or the impact force is decreasing with the moisture content and cushion inclination increasing.The impact force spreads from the point of rockfall to all directions.The impact force data of the experiment is a little large than others,so this method provides a gist for choosing the prevention and cure measure for rockfall.
