摘要
通过采用系统论理念和构造体系观点来研究滑坡群,指出前缘增生组合式滑坡群是最新研究认识的3种基本型式滑坡群中较简单、较常见、较重要的类型;并介绍了该类型滑坡群的平面组合、构图特点和发育特征,分析、探讨了该类型滑坡群的形成条件、形成机理及演化过程;揭晓了增生滑坡为什么会出现在老滑坡或古滑坡的某一特定部位这一滑坡群研究的核心或关键问题,认为解决这一问题就可以把握增生滑体出现在什么部位的规律,从而可为较大尺度滑坡灾害的风险评估和预测、预警分析提供必要的依据。
By using the system theory and the concept of tectonic system proposed by Professor J. S. Lee to study the landslide group, this paper points out that anterior revival type landslide groups are simpler, more common and more important than the other two types of landslide group that we have already known. The paper introduces the characteristics of planar combination and composition and the development character of this kind of landslide group, and analyzes and discusses the condition, mechanism and process of shaping this kind of landslide group. At last the paper emphasizes that it is essential to know why new landslides developed at the special position of old landslides; if this question is answered, we will grasp the rule and provide necessary reference for landslide disaster assess- ment,forcasting and analysis thereby.
