Mountain Highway Slope Stability Monitoring And Evaluation

With the expressway in Jiangxi Province Mountain's rapid development,more and more senior slope occur.Along the highway in various high slope steep terrain and complex geological conditions,slope stability and its protective effect have been to people's attention.In addition to the slope monitoring the implementation of the scene,how to make the monitoring data based on scientific analysis and the stability of the protective effect of the scientific evaluation? Therefore,this study calculated based on modern technology,combined slope engineering geology, structural analysis and on-site testing technology traditional geological theory,laboratory tests,numerical calculation and fuzzy math theory, carry out the following tasks:1.Based on the high slope of Thai-Gan Expressway in Jiangxi K203-K236, investigate the environmental conditions background and establish a database.Turn right along the K203 and K236-K216 high slope stability of the situation and environment-related factors in the background mapping analysis,evaluating the quality of lithologic,stratigraphic occurrence and alignments,vegetation growth,slope protection type are the main slope stability factors.2.A systematic analysis of the high slope protection works and the type of conditions applicable to all types of protection compared the ease of construction,reasonable force such as a discussion on the effectiveness of the project approach.3.Systematically summed up the high slope monitoring the content and methods the application of the Jiangxi Provincial Expressway along the slope different types of monitoring technology and methods.:Sloping surface and the slope deep displacement monitoring component stereo Displacement Monitoring applicable to a large scale,the potential sliding surface deep.Geological complexity of the high and steep slope;slope surface and shallow slope deformation monitoring,applied to the slope of potential sliding surface junior,Sliding face steep angle than the shallow landslide;Stress monitoring of the shelter structure is more applicable to the evaluation of protective effect.Various monitoring techniques mutual coordination,monitoring and effective.4.Taigan Expressway against K211,K203,K236 typical high slope engineering geological conditions,Stability proposed evaluation scene integrated monitoring and laboratory tests,comprehensive numerical analysis.Monitoring technology to local conditions,a combination of various monitoring techniques such as spatial displacement monitoring, deep hole deformation monitoring,earth pressure monitoring, multi-displacement meter monitoring mutual coordination,,regional Slope Stability Evaluation and key sections combining Lot typical numerical calculation and evaluation of regional fuzzy combination. 5.Using Fuzzy Toolbox for Matlab tool,considering the impact of slope stability of the key factors through fuzzy-box Fuzzy Inference System established a fuzzy slope stability evaluation model,achieve a comprehensive evaluation for slope stability,and case evaluation model has be proved to be effective.
