Numerical Simulation Of High Steep Rock Slope Collapses Disease And Anchor Structure Optimization Analysis

Study on landslides is still a hot research topic in the field of geotechnical engineering,but also a complex and fails to solve the technical problems. Landslides is affected by manyfactors, such as such as height, weathering, precipitation, lithology and so on. Meanwhile, inorder to ensure the stability of slope reinforcement after treatment, A large number ofscientists and engineers are working on a variety of methods and strengthening support meanssupporting aspects of the subject a lot of theoretical and experimental tests, and has madegreat progress. In this thesis, the paper is takes the main reseach object by G312line, the maincontents are as follows:(1) The paper summarized and analyzed for slope failure disease research anddevelopment process of bolting structure,the theory supports and promotes research offoundations of landslides.(2) According to the regional environmental geology and disease characteristics of thelandslide section of G312line, analyze the causes of disease.To put forward a plan to harnessdisease, and build and theoretical analysis provides numerical data for the numerical model ofthe paper.(3) Collapse is from continuum to non-continuum, and finally to the progressive failuredispersions. In continuum mechanics based method block discrete spring, which can establisha link between the continuum and dispersion, thereby CDEM selected sections of numericalsoftware to simulate disease may reflect the collapse of the real results. While the simulationresults with local disease characteristics, and summarized the joints and internal friction anglefor the collapse of mudstone disease impact.(4) In the line G312highway slope as a reservoir engineering background, bolt spacingas the analytical parameters of the internal forces anchor structure is analyzed, Further thanelected to anchor bolt spacing as a relative optimum spacing and frame structure of a singleanalysis parameters.(5) Relatively optimal anchor structure as calculated on the basis of quantities, based onthe same engineering, anchor frame structure parameter selection, Such as bolt spacing, boltaxial force, the slope displacement, prestressed, so as to select the most suitable for theproject prestressed anchor frame structure.(6) Supporting the structural basis for the optimal amount determined based on the sameproject, the free segment and anchor bolt segment structure is analyzed in order to determinethe best free section and anchorage length.(7) Finally, the paper summarizes the work done and all the major achievements andshortcomings and suggestions for further research papers.
