Why Engineers Should Not Attempt to Quantify GSI

In the past decade, there has been an increasing trend of digitalizing rock engineering processes. However, this process not accompanied by a critical analysis very same empirical methods that many complex numerical and digital are founded upon. As engineers, we taught to use trust numbers. Indeed, would be able define factor safety structure without what happens when those numbers nothing but descriptions qualitative assessments? paper present review attempts presented in literature quantify GSI (geological strength index). To authors’ knowledge, represents first time all different tables quantification have proposed over two decades collated compared critically. our critique, argue against paradigm whereby adds experience for inexperienced engineers. Furthermore, discuss limitations notion could transform subjectivity into objectivity since parameters under considerations quantitative measurements. Relying on empirically defined equivalences raises important questions, particularly these being used so-called accurate mass classification input design purposes.
