摘　　要：该变形体是一个较独特的倾倒变形问题,它与澜沧江上游河谷其他地段倾倒变形问题的形成控制因素有着较大的不同。通过深入研究该倾倒变形岩体的分布情况、基本形式及变形特征、发展过程及力学机制等方面,本文从地形临空条件、岩体结构、特殊的侧向切割结构面等3个方面阐述了该倾倒变形体特殊的控制条件,并进一步分析了该倾倒变形体的形成发展演化全过程。Unlike others toppling rock mass,it is a relatively unique one on the Lancang River Valley,which has quite different from others in controling factors.This dumping of deformation has studied from the aspects： distribution of fiber length,elemental form cum deformation behavior and developing process cum causative mechanisms.This text has described the toppling rock mass specifically controlled conditions from terrain conditions overhead,rock structure,and the special structure of the lateral cut surface,and analyzed all developing process of the toppling rock mass.
