NettetGSI is estimated from the chart of Marinos et al. (2005); So¨nmez and Ulusay (2002) discuss the sensitivity of the Hoek–Brown strength envelope to GSI. Although relationships exist to convert RMR 89 and Q to GSI (see Hoek et al. 1995), Hoek (2007) recommends that GSI be estimated directly by means of the charts published on its use.
