The Study of the Numerical Simulation in the Evaluation of Slope Stability

摘要

With nearly a hundred years' development,the slope stability has gained a mature method for analysis.But there are great limitations in the traditional slice method,the limit analysis method and the slip hne method.There are also some certain errors during the process of calculation and the result of the value,without the consideration of the influence caused by stress and strain.With the development of the information technology,the numerical simulation methods is widely used in the field of analysis of slope stability,with the consideration of the influence caused by stress the strain.The whole process which can simulate the loading and unloading of slope,the analysis of stress and strain aims to get the solution for the ultimate load of slope.So the slope stability evaluation can directly get the surface of slip slope failure,figure of the strain and stress,figure of the distribution of plastic zones,the figure of shear failure and tensile failure zone through numerical calculation.The engineering practice shows that the numerical simulation combing with the traditional calculation method is more reasonable and scientific.
