2008-5.12地震中,由于当时强烈的地震作用,使得地震灾区地表变形巨大,生态环境严重破坏。地震诱发的地质灾害威胁着灾区人民群众的生命财产安全,震中地区出现的主要灾害形式为边坡的崩滑及崩滑堆积体堵江（河、路）。本文通过对青牛沱崩塌群及崩滑堵江形成堰塞湖的基本特征的论述,分析了其形成机制和产生的危害特征,最后因地制宜地提出了防治对策。为在恶劣环境下的地质灾害评价和防治提供了一套完整的技术思路,也为以后相似情况下的其他地区的灾害评价、防治提供参考。
2008-5.12地震中,由于噹時彊烈的地震作用,使得地震災區地錶變形巨大,生態環境嚴重破壞。地震誘髮的地質災害威脅著災區人民群衆的生命財產安全,震中地區齣現的主要災害形式為邊坡的崩滑及崩滑堆積體堵江（河、路）。本文通過對青牛沱崩塌群及崩滑堵江形成堰塞湖的基本特徵的論述,分析瞭其形成機製和產生的危害特徵,最後因地製宜地提齣瞭防治對策。為在噁劣環境下的地質災害評價和防治提供瞭一套完整的技術思路,也為以後相似情況下的其他地區的災害評價、防治提供參攷。

During 2008-5.12 earthquakes earthquake-stricken area earth＇s surface deformation is enormous,the ecological environment destroys gravely.The geology disaster that the earthquake causes to happen is threatening disaster area safety of the lives and property of the people,the main disaster form appearing epicenter area is that the side slope slumping and slumps accumulate the body stopping up a river（road）.The paper illustrated the essential characteristics of Qingniutuo river collapses,has analyzed it＇s forming mechanism and the threat coming into being,then at last has brought forward the prevention and cure countermeasure in a manner appropriate to local conditions.Valuation and prevention and cure have provided a set of entire technology train of thought to the geology disaster under adverse circumstances,also,other,has provided a reference for similarity condition moves downwards hereafter.
