is a free, lightweight software application developed by Rocscience (a leading geotechnical software company). Its primary purpose is to determine the Hoek-Brown failure criterion parameters for rock masses, which are essential for designing tunnels, slopes, and foundations in jointed rock.

Select the Geological Strength Index (GSI) and the disturbance factor (D) based on site investigation data.

: Includes built-in charts and tables to estimate critical input parameters like: Unconfined Compressive Strength ( σcisigma sub c i end-sub ) .

: Predicting plastic zones and deformation around underground excavations.

When producing a paper using Roclab 1.0, ensure that you:

Define intact rock constant (mi), GSI, and disturbance factor (D). The software computes σci (uniaxial compressive strength) automatically or allows manual entry.
