The Stability Analysis Of The Rock Slope And Researching On The Pile Anchor Support

Slope stability analysis has attracted much attention in the engineering field,the mechanical mechanism of the slope stability and design theory is varied in engineering practice. Combined with an engineering case, this thesis uses the method of combining theoretical analysis and numerical simulation to study the design theory of pile foundation-trimmer beam-retaining wall. The main results and conclusions can be expressed as follows.The theoretical calculation system for slope stability analysis,anti-slide pile internal force and displacement and cable design calculation theory was Summarized. The interior and the exterior of slope stability influence factors were researched. It is concluded that the bending moment is presented first increases then decreases by analyzing of anti-slide pile stress properties.Through the practical engineering example in Beijing,the types of the unstability about the slope rock mass and external factors of the slope instability was researched by analyzing formation lithology of slope, engineering geological conditions, hydrogeological conditions, the types of slope rock mass quality and structure analysis. The engineering measures was put forward through the theoretical calculation of the slope stability, and the design of the anti-slide pile and anchor rope theory calculation.The practical engineering example in Beijing was simulated by means of establishing two-dimensional finite element model through the Midas GTS software.The variety of stress distribution and displacement distribution before and after the slope supporting was compared and analyzed. The theoretical calculation results and the numerical simulation results were compared and analyzed.
