The limit equilibrium model, used in displacement discontinuity codes, is a popular method to simulate pillar failure. This paper investigates the use of physical modelling calibrate this model. For experiments, an artificial material was prepared and cubes were poured using standard 100 mm χ civil engineering concrete moulds. friction angle between platens testing machine varied by soap sandpa...

Slope stability is one of the most important topics engineering geology with a background more than 300 years. So far, various assessment techniques have been developed which include range simple evaluations, planar failure, limit state criteria, equilibrium analysis, numerical methods, hybrid and high-order approaches are implemented in two-dimensional (2D) three-dimensional (3D) space. In mea...

The prediction of reservoir bank collapse width is a unique problem encountered in the construction hydropower projects. Existing empirical graphic methods are based on final state and can be used to predict only width, they thus do not adequately reflect characteristics process. To solve this problem, model for limit equilibrium theory was established, key parameters process were analyzed. res...
