群体滑坡的地质结构类型与发育特征

Geologic structure patterns and development characteristics of population landslide

溯源、剖析、界定了前人关于滑坡群、滑坡带术语的由来、内涵、定义,提出了群体滑坡和滑坡集群2个新的术语,并整合了它们之间的相互关系;初步厘定了群体滑坡的分类方案,确定了群体滑坡的基本组合型式;列举中国南方和北方大量有关的实际例证,逐一介绍了目前已知的5种最基本组合型式的发育产出特征及平面构图特点。认识到研究群体滑坡的科学意义:可拓宽灾害地质的研究视野和内容,将丰富灾害地质研究的已有理论,能为灾害地质风险评估和防治提供大尺度的分析依据。最后强调指出,研究群体滑坡首先必须厘定其组合型式,最终才能揭晓新生滑坡的产生规律。

This paper discusses the origins, contents and definitions of landslip, landslip group and landslip zone and put forward a new word： population landslide. After identified the correlation between population landslide and landslide cluster, classification method and basic combination patterns of population landslide have been determined. Authors introduce development and plane component features of 5 basic patterns by listing a large number of examples from the North and South of China. This population landslide research broadens the field of geological disaster, enriches its existing theories, and provides a analysis for large-scale risk assessment and prevention. Finally, its significance to point out that studying the population landslide researchers must make a combination type well understood at first, then begin to find regular patterns of new landslide.
