Abstract

Abstract: The paper simulates triaxial tests of marble under different confining pressures by the particle flow code (PFC). It is noted that the micro parameters derived from the uniaxial tests can be used to simulate triaxial tests. The comparisons between the results of PFC numerical simulations and laboratory test show good agreement with the tested Mohr-Coulomb strength parameters. However, the PFC simulations could not reflect the change of the elastic modulus in the actual testing. The significant differences also exist in the tested and simulated Poisson's Ratio values.
