This permits optimal adaptation of the nail- ing to the project specific circumstances which has a positive influence of the supporting behavior.This step was an essential mile-stone in the history of rope nets. Due to the freedom of choice in the arrangement of the nailing...

... failure process in the slope are simulated based on the gravity increased procedure while keeping the properties of the slope constant. Numerical results are shown focusing on the dependency of the allowable slope height and possible failure modes on the packing arrangement of circular element...

... and the protection from corrosion have been significantly improved. It is also possible now to arrange the nails independently of the netting size, so that project-specific requirements can be perfectly met. The design of the innovative rock protection system is based on the results of field tests, model experiments...

... of the power plant was made with comprehensive account of the site geology: the machine hall and the transformer bay are arranged in one tectonic block characterized by a uniform stress field. The long axes of the openings are oriented transverse to the layers, in the direction of the maximum stress vector...

... ABSTRACT: The paper examines and compares different schemes proposed for the evaluation of the equivalent continuum hydraulic properties of rock masses. With reference to simple 2D arrangements of two orthogonal joint sets, the equivalent permeability and compressibility parameters...
