.... INTRODUCTION The rock material is a kind of special material. There are fractures in it. The conventional analysis methods, such as like elastic, elasto-plastic, elastic-brittle and viscoelastic method, are fit for ideal isotropic and continuous material rather than rock material[1,2]. So, the rock mass...

... Abstract Based on the fact that the force is a vector, a new method for slope stability analysis is proposed, called Vector Sum Analysis Method (VSAM). In this method, the stability analysis is done on the basis of the current stress state of slope and its whole potential sliding direction...

... ABSTRACT ABSTRACT: A three-dimensional (3D) analysis method of rock block stability, based on the sliding mechanism of arch dam abutment and rock slope failure with multiple rock wedges, is presented. The method of vector analysis was employed in the description of block geometry and force...

... methods and quantitative analysis methods(Huang & Ding 1999). The engineering analogy method is a representative of the qualitative analysis methods and has found extensive application in the engineering practice(Yang et al. 1997). The essence of the method is to apply the available experiences...

... openings will expand with time. In this paper, the range of cracks which were obtained by the Crack Analysis Method and the range of the plastic zone which was obtained by the No Tension Analysis Method were investigated and compared. 1 INTRODUCTION When underground openings are excavated in a rock mass...

... ABSTRACT A simple analysis method suitable for the preliminary design of tunnel supports is developed. The analysis is generally intended for cylindrical tunnels with closed-ring primary support systems excavated full-face in ground masses that can for practical purposes be treated as time...
