What is Geological Strength Index for Rock Masses about?

This document summarizes the Geological Strength Index (GSI), a rock mass classification system developed to characterize rock masses for use in numerical modeling and design of underground excavations. The GSI focuses on basic geological observations of the rock mass to estimate its strength and deformability parameters. It accounts for factors like lithology, structure, discontinuity conditions, and blockiness. The GSI has evolved over time to better characterize very poor quality rock masses and is now w
