摘　　要：文章分析了玛坝整个破坏周边的破坏类型 ,对降落拱坝工作机制的形成作了论述 ,结合过去所论并在本文分析基础上 ,对玛坝破坏可能机制的主要路径进一步作了归结。在长期的累进破坏中 ,变形稳定、渗透稳定和抗滑稳定三者均失稳。The article analyses the rupture kinds of the whole collapse bound,explains the form of the working mechanism of the falling arch.Combining the discussion concluded before and on the basis of analysis in this article,it further puts the main path of the possible failure mechanism in a nut shell.In the long term progressive failure,the stabilities of deformation,seepage and sliding have been lost jointly.
