Study On Design Method Of Single Sliding Surface Of Rock Slope Treatment

Chek Tongkuangyu mine is located in Wenshui County in the west of Northern Loess Plateauregion, is the Shanxi Jindi coal limited company to be in one of the major coal mine in Shanxi County ofWenshui Province, Lvliang City, the construction of an annual output of three million tons. Mine islocated in the central Shanxi Province, the west of Taiyuan basin, Lvliang mountain in Shandong.Because of the proposed site for the mountain west, East West High low, steep slope, the first designer todetermine the shear strength parameters of slope according to the calculation method and experience atthis stage of common values, on the field the west slope, the backfill method. But later appeared again,down slope slope signs again spondylolisthesis, constitute a serious threat to the proposed site. Therefore,accurate prediction, treatment and monitoring of slope stability has important practical significance.With the development of the landslide hazard attention gradually, more and more investment on thetreatment of the slope in China, although the landslide research each year up to hundreds of specificareas, but the landslide still cannot meet the requirements of production, such as: selecting theappropriate method to determine the structure of the shear strength of the interface, select the stabilityevaluation method, control scheme etc.. Each of these links are related to the success or failure of slopeengineering, stability and control of slope in the process of governance be imperative. In this paper, inorder to determine the shear strength of the sliding plane, the slope stability analysis, slope treatmentmethod is chosen as the research object, the three main components of single sliding surface in rockslope were studied.The guiding ideology of this thesis is the application of Professor Dong Zhaoxiang’s "rock slopestability digital dynamic prediction " the book of single sliding surface geological structure in slopestability digital dynamic model is established, the shear strength parameters back analysis of dynamicmodel and the equations of the single sliding surface of slope geological structure considering seismicforce, based on the geological parameters of shear strength and stability coefficient and control designmethod is closely related to the geological structure of the slope of the sliding surface.Through application in slope Chek Tongkuangyu mine, verified the "rock slope stability digitaldynamic model" as the theoretical basis for the feasibility of the inverse analysis method, more embodiesthe superiority of the method, provides a new idea and approach for the management and design ofslope.
