Research On Optimum Design Of The Highway Slope Disposal Method

The slope is one of the most familiar of natural geological environment.Slope engineering relates to all aspects of national economic construction, such as the open air mining engineering, railroad, highway, water conservancy,construction engineering and civil construction,On one hand it determines the safety and in gear use of all constructions which it support,on the other hand it influences the cost of the building.The disposal of slope is an engineering of defend disaster of complex technique and difficult construction. It is important to optimum design of the slope disposal method.Considering the specific of the highway,a classification of the slope is suggested. This passage introduced the method of the slope stability analysis. The reason of the highway slope coast is also analyzed. And this paper introduced the slope disposal method.The passage introduced the basic theory and the characteristic of the optimum design. According to the optimum design of the slope angle , the method for determining the most optimum slope angle has been analyzed., which is used to guide the construction of the engineering and some good treatment effects and economic benefits have been obtained,Taking the influence of the slope and sliding surfaces obliquities into account,a new method for determining the orientation angle of prestressed anchor cable is presented.Two practical projects in the Ganyue Highway TaiGan And GanDing were selected as the cases and discussed the methods of disposal slope, design principle and optimization.And got the basic process deas and methods in order to guide the project's construction.
