滚石与滚石灾害

长期以来 ,滚石灾害是一种很少受到重视的地质灾害。本文从滚石的概念出发 ,对滚石的内涵、外延及特征进行了较为深入的论述。实际上 ,将各种动力地质现象涉及到的滚石问题提出来单独进行研究不仅有助于问题的简化 ,还有助于研究的深化。自然变异或人为扰动引发的滚石可能会给人类活动和社会造成一定的损失 ,而将滚石作为一类地质灾害并称之为滚石灾害是合理的 ,也是合适的。本文最后还给出了国际上滚石研究的主要方向与基本问题 ,为进一步研究提供参考

ROCK FALLS AND ROCK FALL HAZARDS

Rock fall, a geological hazard, has not attracted attention of researchers for a long time. This paper first introduces some concepts followed with connotations, extensions and characteristics of rock falls. In fact, rock falls can occur during various dynamic geological phenomena. Both natural forces and human activities can cause rock falls, which may result in losses of human lives and properties and may affect the development of communities. Therefore, this paper focuses on the rockfall itself, which can help us not only to simplify the resolution of the problem, but also gain a deep insight into mechanisms of rock falls. The authors then recommend that rock falls be treated as one type of geological hazard, i.e. rock fall hazard. At the end, the authors also summarize current research focuses and fundamental issues related to rock falls in the world.
