Az előadás címe:  The use of directional shear strength models in 2D and 3D limit equilibrium analysis to understand complex failure mechanisms in heterogeneous rock slopes

Az előadás rövid összefoglalója: Slope stability modelling techniques have evolved over the years and increased in complexity with continuous improvements in computing capability and available software. Less than 20 years ago, basic kinematic analysis was the primary means of designing large rock slopes. In the 2000s, the use of two-dimensional limit equilibrium analysis and numerical modelling rapidly increased with faster computing. As we approach the 2020s, three-dimensional limit equilibrium and finite element analysis software are readily available and now offer a range of options to model the behavior of complex, heterogeneous rock masses. The results obtained by these different modelling approaches, for example, isotropic versus anisotropic, or 2D versus 3D can vary significantly depending on the geological conditions. The presentation focuses on the use of simple directional shear strength models to apply engineering geological logic to slope stability models and thereby remove the ‘isotropic’ assumption that is often intrinsically associated with slip-circle methods.
