Stability Analysis And Optimized Designing Of Supporting Structure Of Rentuo Landslide In The Three Gorge Reservoir Area

This article embarks from the project actual need, systematically studys the various methods of slope stability analysis, scientifically analyzes the different roles of several supporting structure in slope treatment project.First, Sweden method, Bishop method, Transfer coefficient method and other methods of slope stability analysis are introduced in this text, and their respective applicable conditions are analyzed.Secondly, design steps of anti-slide pile, various factors need to be considered, and design method of retaining wall are briefly introduced. Different design calculating method and applicable conditions of anti-slide pile with anchor,cantilever pile,embedded anti-slide pile are enumerated.Thirdly, this article takes Slope of Rentuo in Chongqing Three Gorges Reservoir area as the research background, rests on the geology background investigation, unifies the indoor and outdoor experiments, analyses the slope body glide scope, the scale, slippery belt soil characteristic, depth, distortion destruction sign and so on. Each kind of condition which affects the slope forms (terrain landform, formation lithology, hydrogeological conditions, human activity and so on) are analyzed carefully one by one, determines the leading factors and derivational factors in the landslide forming process. The stability of Rentuo landslide are calculated under main load composed using transfer coefficient method.Finally, the remaining glide-thrust calculated by the transfer coefficient method, and considering other load combination, carrying through optimized design to the anti-slide pile using ANSYS, thereby,we can gain the best pile space,pile diameter and socketed depth. Any more, combining with other treatment methods, such as:draining engneering,slope protection engneering and so on.determining a overall supporting program of Slope of Rentuo.
