Abstract

High Cut Slope reinforcement and protection programs preferred involving civil engineering, geotechnical engineering, restoration ecology, botany multidisciplinary, it includes not only the strength of the structure, stability and deformation problems, also involving social, economic and environmental and ecological problems. For a specific engineering geological conditions, surrounding environment and resource constraints cutting steep slope protection program, how to choose a safe, reliable, economical and reasonable, but you can not find many of the practical methods of environmentally friendly low-carbon program. This article theoretical guidance, modeling and engineering research combined harbor for cutting high slope reinforcement and protection program evaluation of a more comprehensive and reasonable exposition and analysis. In this paper, the big wide highway Guangdong Section of the engineering and construction goals, establish the preferred index system suitable for the project of a High Slope reinforcement and protection programs; introduction of fuzzy comprehensive evaluation of a High Slope Bracing Scheme method and fuzzy comprehensive evaluation model, the weight of each index value is calculated using analytic hierarchy process; take advantage of this model is that the YK17 225-YK17 620 the right side of a High Slope support program evaluation. This study includes the following sections: the first systematically summarizes cutting high slope supporting technology development and reinforcement and protection structure type and its applicable conditions, as well as programs preferred the status quo; analysis routine highway cutting high-side slope excavation and support methods and propose a new concept of cutting high slope excavation and support. And reflected in the selection of the index system and the preferred method of determining the requirements of the new concept. Second study impact factors and predecessors of a High Slope support options proposed index system for comparative analysis, combined with the requirements of the Guangdong Section of big wide highway cutting high slope of the actual situation and new ideas to improve and establish suitable to the Bracing Scheme in the project cutting high slope indicator system. The third is introduced into the fuzzy comprehensive evaluation method and analytic hierarchy process evaluation of High Cut Slope Support program and the establishment of secondary fuzzy comprehensive evaluation model. The index system using AHP to determine the weight of expert scoring method to determine the degree of membership of each evaluation grade. This method is easy to understand, easy to operate, and has a certain practical value. Fourth and finally established fuzzy comprehensive evaluation model is applied to the big wide highway Guangdong Section the YK17 225-YK17 620 right of the typical cutting high slope support program preferred, and a qualitative analysis of the pros and cons of each program and quantitative evaluation. The successful application of fuzzy comprehensive evaluation model established in the big wide highway Guangdong Section of a High Slope reinforcement and protection programs preferred support program decision-making along many cutting high slope better reference value.
