Slope Stability Analysis And Ecological Protection Design Of Classified Highway

With the rapid development of the road constructions in our country, the slope stability analysis and ecological protection design of rocky slope of highway are of great importance in highway building in hilly area. In this paper, it is thoroughly discussed that rock slope stability of rocky highway surface protection of rocky slope, which bases on the research project of the second-class highway between Gui Yang county and Jia He county. Hunan University and Chen Zhou Classified Highway Construction Limited Company have operated the research project. The theme-group discusses systematically and thoroughly the research on rocky slope stability analysis and ecological protection design.By analyzing rocky slopes built at home and abroad, the theme-group not only summarizes the analysis methods of rocky slope and ecological protection, but also points out some questions which have not been solved yet. Considering the characteristics of rocky slopes, this paper discusses the stability analysis of rocky slopes, the searching methods of its corresponding critical slip surface and the factors affecting the stability of rocky slope. On the basis of the experiences on ecological protection of slopes at home and aboard, this paper proposes a working way fitting for the second-class highway between Gui Yang county and Jia He county. It also discusses thoroughly the mechanism of ecological protection basing on the research. Besides, during the research period, combining theory of analysis with practice of building the road, the theme-group succeeds in the research on stability analysis and utilizes some new methods in building the second-class highway. In soil engineering experiment, the theme-group has obtained a lot of valuable datum which will be much helpful in building high-type highways in western China in the future.
