... Abstract Fracture pressure in traditional wellbore stability analysis is based on tensile failure. When the drilling fluid density is high, there is not only tensile fracture but also shear fracture may occur on the wellbore wall of horizontal wells. The possible fracture modes of horizontal...

The relationship of the induced plastic zones, crest displacements varying with these fault parameters was established. The distribution of plastic zone and displacement...

... Abstract Soil-rock mixture is different from conventional soil and rock materials. Inhomogeneity is an obvious feature of soil-rock mixture and the material component is one of intrinsic factors to influence the stability of soil-rock mixture slope. Mathematical intervals are defined for sort...

... Abstract To evaluate the surrounding rock stability in steeply dipping seams, based on the detection technology of soundwave and electromagnetic wave, the quality of surrounding rock and separation area location for roadway are identified. The degree of fracture for the inner wall of holes...

... Abstract Since 1990s, researchers in the discontinuous deformation analysis (DDA) community have dedicated a great deal of effort on the stability analysis of slopes, tunnels and caverns. This paper contains a summary of more than 80 published papers or theses concerning stability analysis...

... and seismic slope stability analysis confirmed the global stability of the slope. However, the rock slopes are highly jointed and the joint spacing and orientation are varying at different locations. Hence it is very likely that there could be wedge failures possible at some of the pier locations. This paper...
