Three-Dimensional Stability Analysis Method For Reinforced Slope With Anti Sliding Piles Based On Minimum Potential Energy

As an effective engineering measures in landslide treatment of stabilizing pile,has been widely used in the prevention of geological disasters of landslide,At present,the research on analysis methods of stabilizing pile reinforced slope stability also is in ceaseless development and improvement.According to the homogeneous slope with arbitrary sliding surface,no need to partition strips,a three-dimensional slope stability analytical of minimum potential energy method of Reinforced by stabilizing pile is put forward. a three-dimensional arbitrary sliding surface construction and method of the critical slip surface search is put forward based on the principle of minimum potential energy.combined with national natural science foundation of China(NO.51304084),this paper focuses on the study of three- dimensional stability analysis method for Reinforced slope with anti Sliding Piles based on minimum potential energy,The main research contents include the following aspects:(1) For the homogeneous slope with arbitrary sliding surface,taking the sliding body as a whole,a three-dimensional calculation model of Reinforced by stabilizing pile is established for Considering the interaction between stabilizing pile and slop, then obtain the total potential energy of the whole slope system.based on the principle of minimum energy obtained the slide safety factor.through the reasonable choice calculation method, a three-dimensional slope stability analytical method of Reinforced by the multi row stabilizing pile are put forward.Based on an example of contrast, verify the feasibility andpracticability of the method.(2) a three-dimensional arbitrary sliding surface construction method by using 6parameters control is put forward.Through with the established a three-dimensional slope stability analytical of minimum potential energy method of Reinforced by stabilizing pile combined,established the objective function to search,design of a three-dimensional slope of Reinforced by stabilizing pile critical slip surface search procedure based on genetic algorithm.(3) In order to simple calculation,developed on a three-dimensional slope stability analysis program of Reinforced by stabilizing pile based on matlab for above established a three-dimensional slope stability analytical method of Reinforced by the multi row stabilizing.(4) The analysis method is applied to the specific project example, verified the practicability of this method in Engineering.
