The premise

RocLab is a very useful piece of free software written in 2011 for determining rock mass strength parameters, based on the generalized Hoek-Brown failure criterion (Hoek et al. 2002). The main problem is that it is discontinued and the only version is available for windows. With this project I want to archive the same objective as RocLab’s using python to increase the overall accessibility of the program and improve the plot’s interfaces (thanks to matplotlib).

Capabilities

• Calculate Hoek-Brown criterion parameters
• Calculate Rock mass parameters ($\sigma_t$, $\sigma_c$, $\sigma_{cm}$, $E_{rm}$)
• Calculate $\sigma_{3}^{max}$ based on different applications (e.g tunnels)
• Calculate Mohr-Coulomb parameters (c and $\phi$)
• Plot H-B and M-C envelope.
• Plot failure mohr circle and calculate the $\sigma_{1}^{max}$ value.

Future additions:

• Tabulated list values for D
• Tabulated list values for $m_i$
• Import data
• Export data
