摘要
高速远程崩滑动力学机理的研究,一直是国内外工程地质与山地灾害领域崩塌、滑坡灾害研究的前沿热点问题。对这一研究领域,最近几十年来所取得的研究成果、研究现状及发展趋势进行了述评。厘定了高速远程崩滑的定义;详细地阐述了国内外众多典型重大高速远程崩滑灾害事件的几何学、运动学特征;概述了迄今为止所提出的高速远程崩滑形成的各种动力学机理;分析与讨论了高速远程崩滑动力学机理研究的发展趋势与动向;提出了今后进一步研究的总体思路、目标与应重点解决的关键问题。
In the realms of engineering geology and mountain hazards, study on dynamic mechanism of rock avalanches is one of the hot spots all over the world. In this paper, the authors reviewed the achievements obtained, current status and developing trends on dynamics of rock avalanches over the past decades. Firstly, a definition for rock avalanches was given, and the nature of case histories of rockfall-avalanches and rockslide-avalanches occurred at home and abroad was introduced in detail. Then the present mechanisms of release, disintegration, and displacement of rock avalanches were outlined, as well as its developing trends were analyzed. Finally an overall thinking for directing study and key problems solved in further research were proposed.
