Study On Safety Control Method Of Side Slope Of Stratified And Decency Gravel Rock

With the acceleration of implementing the Great Western Development Strategy, constructions of highway will be more, especially super highway. At the same time ,the excavation of super highway's slope had grave influences in it's blocky and environment .If we do not study these influences and take operative measures ,it will have grave consequences when construct and operate super highway. So ,it's very important to bring up safety control method of side slope .This paper firstly give a summary of the development of side slope and the manage of side slope, especially analyze the finite difference method and prestressed anchorage method. Then systematically explain and analyze the stability theory of side slope, including the factors, destruction forms and analysis methods in the stability theory.Secondly, depending on BT-17 contract section of BaoTian super highway, based on analyze the background of this construction, get by series experimentations, norms and experiences ,then we have the mechanics parameter and other parameters for the numerical calculation. With the Fast Lagrangian Analysis of Continua method, through the numerical calculation for original state of this slope that based on geology analyze and series parameters , we have the slope's sliding surface .Based on these dates and analyzes ,it bring up safety control method of side slope ,and make an evaluation for the geology safety control which we have the conditions now. And it's safety meanwhile economically to take these methods for this side slope.
