Ultimate bearing capacity at the tip of a pile in rock based on the modified Hoek-Brown criterion

- A method for calculating the ultimate bearing capacity at the tip of a pile is presented.
- Ultimate bearing capacity is generalized for the modified Hoek-Brown criterion.
- Perfect plasticity, isotropy, weightless rock media, without inertial forces, Meyerhof׳s hypothesis are considered.
- All the formulation can be programmed in a spreadsheet.
