Abstract: Rockfalls featured by burstiness and uncertainty are one of the most prevailing natural hazards in the mountainous regions of China. Research of the rockfalls disaster is relatively backward in China at present, and the key technology is insufficient in the field. In this paper, the formation dynamic evolution mechanisms of rockfalls were revealed based on the geological mechanical model, and the dynamic responses of rockfalls impact protective structure were studied. Furthermore, series energy consumption structures and materials were developed. These achievements were applied widely in various fields. Combining the demonstration projects, the technical system of rockfall preventions was established.
