Slope Safety Evaluation Method Of Anchoring In Reinforcement Under Strong Earthquake

China is one of the most populous country in the world, relatively densepopulation distribution, at the same time, our country is a mountainous area accountsfor about2of the nation’s land area3mountainous country, as the saying goes, as ifmountainous earthquake; seismic geological disaster, one can imagine what kind ofconsequences.Implementation of the development strategy of western development, particularlyat the country, while the west is the most widely distributed in the mountains, thisanalysis is critical to security and stability of the slope under earthquake, so far, on theslope of governance the most important the project is to reinforce the slope, the mostwidely used and most effective is the prestressed anchor cable reinforcement measures.Based on this, to carry out research in the earthquake on the anchor cablereinforcement slope safety evaluation method. Safety assessment is a comprehensiveapplication of the safety systems engineering method for running slope safety measureand forecast of slope, the potential risk of qualitative and quantitative analysis, theslope to determine the possible danger probability and its severity, and put forward themost effective prevention measures to ensure the safety of the project.First introduced the seismic slope stability analysis methods, and Study on slopedynamic safety evaluation of the stability safety coefficient calculation method.Ultimately determine the Sarma method and FLAC software based on the analysis ofthe strength reduction method for strong earthquake of anchor reinforcement slopesafety evaluation, according to the existing research staff analysis modelled, further tobe improved, in-depth study.Through the analysis of that, in the natural, slope due to earthquake seismicintensity increased with progressive instability, loss of stability. While in the side slopeanchor cable reinforcement after the earthquake, slope stability improvement, safetycoefficient is raised, the whole slope stability evaluation.So the research of slope safety assessment methods to the quake-prone region hasimportant practical significance and value.
