AbAbstract万方数据万方数据With the development of slope engineering in our country, we have been investing more and more on the project management of slope. Slope engineering will be successfully managed when the conclusion of slope stability analysis is reliable and the control method of slope engineering is feasible.In this paper, we’ll take Guanyinshan slope engineering in Longsheng town as study object, and adopt the method of theoretical analysis and practical application. In this way, we can study for analyzing stability and advance the program on treating technique for slope engineering.Firstly, introduce the study of slope engineering and discuss the history of slope stability analysis as well as the slope control technology.Secondly, based on the full collection of relevant information and identify relevant engineering geological conditions of Guanyinshan slope engineering in Longsheng town, point out the main factors of landslide is the slippery slope instability geotechnical properties of the body itself , the structure and topography of the terrain , surface water and irrational human activities.Thirdly, use a variety of method to solve the factor of safety, the calculations show that,take 2-2 main sections for example, in natural state, the result of the Swedish slice method is 1.150 , the result of simplify Bishop method is 1.197, the result of Janbu method is 1.226, the result of FLAC3D strength reduction method is 1.24; in the state of storm, the results are 1.050, 1.093, 1.120 and 1.13. Based on the results, in natural state , the slope is stable; in the state of storm , the slope is basically stable.Fourthly, use the software of FLAC3D to discuss the slope stability of 2-2’ main section,in natural state, the slope deformation is mainly caused by Gravity in vertical, and velocity vector distributes widely; in the state of storm, the slope deformation gradually increased to the outside slope, and velocity vector focuses outward of the slope obviously.Fifthl
