Soil and Rock Slope Stability Analysis based on Numerical Manifold Method and Graph Theory

Limit equilibrium method, strength reduction method and Finite Difference Methods are the most prevalently used methods for soil and rock slope stability analysis. However, it can be mention that those have some limitations in practical application. In the Limit equilibrium method, the constitutive model cannot be considered and many assumptions are needed between slices of soil and rock. The strength reduction method requires iterative and continual calculations and does not give the slip surface directly. For slope stability analysis a new method based on the numerical Manifold method and Graph theory is this research developed that can directly calculate the potential critical slip surface and minimum safety factor according to the stress results of numerical simulation. This method is based on current stress state and can overcome the disadvantages mentioned above in those three traditional methods.
