Finite Element Analysis of Slope Stability Based on Genetic Algorithm

A method for slope stability calculation was introduced.FEM software Marc was adopted to calculate the stress on the slope,and geometrical non-linearity and material non-linearity were considered.The slip surface was simulated with a broken line.The program was composed based on genetic algorithm.It searched the nodes on the broken line with the minimum safety factor,and the most dangerous slip surface was found.Compared with traditional methods for slope stability,this method abandons the assumption of circular slip surface,takes into account the stress of the slope,and can better simulate actual condition.Comparison of the calculations shows that the results of the new method are more reasonable.
