... (e.g. joint elements in FEM), they are only applicable for less jointed rock mass where little displacement is expected [7, 8]. To deal with inherent discontinuities in the rock mass and possible rupture in the intact rock, discontinuum methods prove to be best till date. Discontinuum methods are based...

... properties. As for the analytical part, the basis of the new analytical solution for the prediction of the load displacement curve was developed. Derived mathematical equations enable calculations of grout displacement in elastic and elasto-plastic behaviour. In the experimental part, four examined bolts...

.... Ensuring the stability of the well is very difficult under such conditions. The proper determination of the state of stress, strain and displacement of the rock mass around the hole is critical in the design of directional holes. Numerical analysis tools which take into account the structure of the rock...

... Abstract Monitoring of pillar and roadway deformations is one of the most important issues in geotechnical engineering and mining practice. The use of 3D laser technology is ideal to monitor strata displacements in underground excavations enabling complex spatial data capture of the entire...

The calculated vertical displacements of cavern roof and wall by FEM analysis were compared with those values monitored during excavation. The calculated axial forces were far below design capacity of rock bolts. The strong rock mass...
