| Abstract: | 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. |
