... convex, concave, those with cavities and/or holes, and probably their unions. In stability analysis of rock-masses, especially for jointed rock tunnels, one of the primary bottlenecks is discontinuous computation of the contacts between arbitrarily shaped polyhedral blocks. The original contact detection...

... stability analysis is carried out by limit equilibrium method. The overburden slope of the quarry is mainly characterized by sandstone which is fractured and weathered. The mine is mostly covered by black cotton soil. Well fractured rock mass, existing open cast working have made the geo-mining condition...

..., the unstable slope is predicted successfully, which cause no casualties. Therefore, the stability analysis of rock slope is the key to solve and control these rock mechanics problems. The factors affecting slope stability include rock hardness, rock integrity, groundwater and rainfall, initial rock stress...

... (DDA) was developed and extended to the elasto-plastic simulation code. In this paper, an application example of NMM-DDA to an actual problem in the Angkor ruin is provided. The stability analysis of the Bayon Central Tower, one of the most important masonry monuments in the Angkor was carried out...

... rock block are essential for the design of underground excavations in jointed rocks. Traditionally stability analysis involves a tetrahedral block formed by an excavation free face and the mean orientation of three rock joints and this is termed as the deterministic analysis. However, the orientation...

At first, to achieve this purpose, the curved-shape discontinuities modeling method was developed to simulate the geometrical model. Then the ordinary method of slices...

... * Corresponding Author s E-mail: mohtarami@ut.ac.ir ABSTRACT The stability of slopes during and after excavation is always a significant issue in the field of rock mechanics. The blocky-flexural toppling failure is one of the most probable types of instabilities in rock slopes. The stability analysis of toppling...
