Stability Analysis of Slope Reinforced with Piles by Global Analysis Method
摘要
Abstract
To analyze the stability of reinforced slopes, on the basis of the global analysis of slope stability, a new procedure is proposed to compute the factor of safety of slopes reinforced with piles. By taking the whole sliding body, instead of individual slices, as the analysis object, three equilibrium equations are formulated according to the moment equilibrium conditions. But in traditional method, we establish two force equilibrium equations( horizon⁃tal direction and vertical direction) and one moment equilibrium equation at a given point. By using the new meth⁃od, we can obtain unique real number solution of the equation and positive safety factor. This method is not only suitable for slopes with slide surfaces of different shapes, but also possesses excellent numerical properties with a very large scope of convergence and a very rapid convergent rate.Moreover, it can be easily extended from two⁃di⁃mension to three⁃dimension. Finaly, two examples are given to prove the effectiveness of this method.关键词
