The program is a free Matlab software dedicated to the estimation of Equivalent Tunnelling Mohr-Coulomb Strength Parameters for Generalized Hoek-Brown Media.

This code is freely distributed for use in an academic and research framework. The humble programmer hastens to say that he cannot be held responsible for any malfunction of the software and related consequences. However, he may provide assistance if needed and kindly asked.

The theoretical background is developped in the journal paper entitled "Robust Equivalent Tunnelling Mohr-Coulomb Strength Parameters for Generalized Hoek-Brown Media", by Meng et al and to be published in European Journal of Environmental and Civil Engineering.

Code-users are encouraged to refer to this paper for any theoretical concern. Besides, we kindly require this articleto be cited if this software is to be used in any published work.
