RESEARCH MECHANICAL CHARACTERISTICS OF THE CORAL ROCK MASS BY AUTOMATIC TRIAXIAL TEST SYSTEMS COMBINE WITH HOEK-BROWN FAILURE CRITERION

Abstract

This paper introduces the determination method of mechanical characteristics of coral rock mass basing Hoek-Brown failure criterion by RocData software. The input parameters are determined by triaxial test results on coral rock specimen, the geological strength index GSI and disturbance factor D. The results of article have practical meanings to research and recommend the calculation values of the mechanical parameters of coral rock mass for designation and excavation the constructions.
