摘　　要：链子崖危岩体距三峡大坝仅27km，一旦失稳，将危及大坝运行和长江航运的安全，加强对该危岩体变形破坏机理的研究具有特定的现实意义。以一直存在缓慢累进位移变形的链子崖T0～T6缝段危岩体为研究对象，结合多年的岩石力学试验成果和变形监测资料，对其变形特征进行了分析，井选取变形相对明显的T5-1至T6缝段危岩块体进行了稳定性计算。Lianziya dangerous rock mass is only 27 kilometers from Three Gorges Dam. Once destablhzed, the operation of Three Gorges Dam and the safety of Yangtze River shipping will be affected. Therefore, studying the deformation and failure mechanism of this dangerous rock mass is of certain practical significance. Based on studying the dangerous rock mass in T0 -T6 fracture sections with long-term slow progressive displacement, the deformation mechanism is analyzed combined with rock mechanical test result and deformation monitoring data of many years. And, the stability of dangerous rock mass in T5 -1- T6 fracture sections with relatively obvious deformation is calculated.
