Stability Monitoring And Protective Evaluation Of Ankang-ShanchuanHigh Rock Slope Of Expressway

The existence of highway rock slope is always a highway operation safety restriction factor, evaluation rock slope stability is also more complicated and necessary research content. Based on the boundary to shan sichuan ankang along rock slope as the research object, the condition of regional geological environment, and a comprehensive analysis on the topography, stratigraphic lithology, geological structures, hydrogeological condition and weather characteristics. The in-situ monitoring and stability analysis method to evaluate the combination of rock slope stability condition, puts forward the protective evaluation scheme. This paper mainly analyzes the well-being to shan sichuan bounded highway K252 section highsteep slope and its protection engineering, on-site build slope table displacement monitoring displacement, deep, and the protective structure implement numerical analysis, and puts forward the high slope stability comprehensive evaluation method. Specific namely:(1) Through the investigation of sichuan world peace to shaanxi along the highway slope regional environment, established a relational database, and then discusses the influence on slope stability, the sensitivity of the factors of slope preliminaris master deformation and development pattern, for rock quality grading.(2) System summary analysis of the existing high slope monitoring technology and method, using GPS slope table with the displacement monitoring embedded deep slope inclined pipe measurement method combining the displacement monitoring site monitoring, based on the analysis of the monitoring data, combined with the calculation and simulation results and scientifically LiangBianPo stability to lie puma assessment and prediction.(3) considering the main factors influencing slope stability of typical section, slope stability assessment model established by numerical analysis and calculation of slope stability and to achieve the comprehensive evaluation, protective effect on its proposed best protection scheme.
