... Abstract Evaluation of the distribution of fractures in a rock mass ahead of a tunnel face is required for safe and reasonable tunnel excavation. To evaluate not only the position of fractures, but also their inclination before tunnel excavation, a directional borehole radar may be a suitable...

... Abstract Portal sections of road and motorway tunnels are usually the most demanding parts of tunnel construction because they are usually executed under inclined surface and, in most cases, in areas with poor rock quality. Currently, there is a limited number of investigation on the stability...

... Abstract A new scheme for measuring and simultaneously visualizing inclination of a rock structure is proposed. A mirror is installed in a mobilized zone in such a way that an observer can identify a light source in the mirror. If then the mirror rotates by a small amount due to movement...

... of the rock slope against plane failure. The expression considers several parameters that govern the stability of the slope. These parameters are: inclination of the slope face, inclination of the joint or discontinuity plane, unit weight of the sliding rock mass, shear strength parameters of joint materials...
