Grouting of Rock Masses
The grouting of rock used to be a quite empirical constructional technique aimed to improve somewhat the physical properties of the masses, which are actually part of the civil engineering project. Different "grouting schools" or "ways of thinking" did develop and a considerable number of recipes were dictated by "great old men" and enforced later on by regulations of any kind. Only in the last...

15 صفحه اولNumerical Investigation of Effect of Rock Bolt Angle on Shear Behavior of Rock Bridges
In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...
