Abstract

Quantitative study was conducted on the GSI score chart in the Hoek-Brown criterion. A new quantitative GSI chart was established and the problem that volumetric joint count of rock mass could not be accurately determined was solved. The rock mass integrity index was used to replace the rock mass volume in order to solve the problem in proper quantitative value determination for the rock mass integrity. This chart also applied the interval number theory to indicate the uncertainty of the geological strength index，which was better in line with the actual situation of onsite value determination for the mechanical parameters of rock mass. It took into account the operability in selective acquisition of field test data and combined multiple indexes to determine the final intersection set of GSI，ensuring the reasonableness of quantitative GSI value determination and providing a theoretical basis and a transition bridge for proper acquisition of field mechanical parameters of rock mass based on indoor rock mechanics tests.

Key words： rock mechanics geological strength index(GSI) Hoek-Brown strength criterion quantitative volumetric joint count
