Analysis Of High Slope Seismic Stability For Highway In Dian Xinan Region

Based on the highways of Dian Xinan region “Da Li ~ BaoShan” and “BaoShan ~ LongLing”, this paper, according to the seismic stability of highway high slope, has carried out the review of the home and abroad related date and the investigation along the slope, summarized and analyzed the Seismic stability factors and protective measures, and numerical analysis for slope, including the following aspects:1. Through field investigation, combined with the local generalgeology and earthquake history, carried on statistics and classification of the slopes along the road, and analysised and summarized the Factors affecting the seismic slope stability, preliminary analysis of the failure mechanism of high slope under the earthquake.2. Using numerical analysis software Midas/GTS, established seismic numerical analysis model of high slope, analysised the influence of rock slope displacement and the PGA amplification factor under the change of slope Geometric and earthquake factors, the different of Slope red layer dip, thickness and location and other factors contains the red layer according to establish models, select parameters and set boundary conditions.3. Summaried the slope reinforcement type and the slope protection form of support projects, discussed their characteristics and conditions, facilitate the design selection for slope reinforcement and protection of similar projects.Separately analysised the reinforcement of anti-slide pile and anchor two support modes, carried out numerically analyzed of red layer, And compared the strengthening results.
