Geological Strength Index (GSI) | How to Use It in Practice for Mining and Civil Engineering

Geological strength index (GSI) was introduced by Hoek (1994) to estimate the reduction in rock mass strength for different geological conditions. It is commonly used in geotechnical, civil engineering and mining to assess the rock mass structure. GSI provides a number which, when combined with the intact rock properties, can be used for estimating the reduction in rock mass strength for different geological conditions. GSI is commonly used in mining engineering and civil engineering, especially geotechnical engineering and engineering geology, to estimate the strength of rock mass. #civilengineering #geotechnicalengineering #mining #engineeringgeology Watch this video to learn how to use GSI to estimate the cohesion and friction angle of rock mass    • Rock Mass Strength: How to Estimate Cohesi...  .
