滚石灾害研究现状及发展趋势

Present Research Status and Development Trend of Rockfall Hazards

滚石是我国西部山区常见的一种地质灾害,它分布范围极广,发生突然,频率高,严重威胁其周围的人类以及各种构筑物。目前,国内外有关滚石的理论研究比较薄弱,以致滚石灾害的防治工作受到严重的影响。基于对国内外大量滚石灾害研究资料的分析,将其研究现状概化为滚石风险分析、滚石运动轨迹、滚石冲击力以及滚石防护等4个方面。据此对滚石研究的发展趋势进行了探讨,以便为滚石灾害的机理研究和治理提供参考依据。

Rockfall is a common disaster in western mountainous region. It badly threatens the people and the various constructions around it because of its wide distribution range, abruptness and high frequency. At present, due to the weakness of theoretical research on rockfall, the prevention and control means of rockfall have been affected badly. On the basis of analysis on rockfall hazards at home and abroad, the studies on rockfall are classified as four aspects, risk analysis, rockfall trajectory, rockfall impact force and rockfall prevention. The development trend of research on rockfall is analyzed. The results can be used as the basis for research on mechanism of rockfall disaster and rockfall control.
