崩塌滚石灾害是中国西部山区一种常见的地质灾害类型,具有突发性和随机性的特点,是山区地质灾害防治的难点和薄弱环节。针对中国崩塌滚石灾害基础研究薄弱,减灾关键技术研发能力不足的问题,开展了崩塌滚石灾害形成条件与形成力学机理的研究,研发了系列耗能减震崩塌滚石灾害防治的新技术。结合汶川地震、芦山地震崩塌滚石灾害防治难题,建设了崩塌滚石灾害防治新技术的试验示范区,并取得了良好的防护效果,为地震灾后重建和崩塌滚石灾害防治新技术的推广应用发挥了重要的示范作用。
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.
