Slumping mass is a special geological disasters mass which occurr deformation and failure under the interaction and mutual influence of the two movement form that collapse and sliding of rock and soil. Generally, they are large in scale and in the event of deformation and failure, will utter a serious threat against the life, property and construction poses of people, resulting in huge economic losses and social impacts. Therefore, in-depth analysis and study on the formation mechanism and failure modes of the slump-deformed mass, and then put forward reasonable teaatment scheme to guarantee people’s lives and property and construction and development of the national economy is very important practical significance.This thesis takes the Baotaliang ultra-high rock slump-deformed mass in Zhenping county as the research object, on the basis of investigation of the wild scene and detailed analysis of existing material,detailed study on the slump-deformed mass’s geological of geological environment condition, form conditions, the formation mechanism and failure modes. Then, respectively use limit equilibrium principle based on the transfer coefficient method and finite element of the shear strength reduction to analyze and calculate it’s stability. The concrete contents are as followed:(1)Firstly, introduce the geological environmental conditions, deformation activity and collapse deformation current development sliding scale of the Baotaliang slump-deformed mass.(2)On the basis of study on the geological environmental conditions of the Baotaliang slump-deformed mass, detailed analyze it’s form conditions, the formation mechanism and failure modes.(3)Respectively use transfer coefficient method based on the limit equilibrium principle and finite element of the shear strength reduction to analyze and calculate it’s stability. The result shows that the slope stability coefficient Obtained by both methods is insignificant, indicate the relevant calculation parameters and calculation model are relatively close to the actual situation, thus the conclusions are reliable. (4)Comprehensively analyze the current commonly used for the sliding masses to prevent and control measures of slumping mass. Considering the specific conditions, put forward the optimum treatment scheme.(5)On the basis of study on dynamic monitoring of the slope, put forward the specific monitoring program in the construction process and construction is completed.
