Abstract

Abstract

This paper proposes that both macroscopic and mesoscopic flaws should be considered in the dynamic damage constitutive model for the jointed rock mass. Firstly, the calculation formula of the macroscopic damage variable (tensor) of the jointed rock mass is deduced based on the energy principle and the fracture mechanics theory so that the geometrical and mechanical parameters can be considered at the same time. Secondly, the compound damage variable (tensor) including both macroscopic and mesoscopic flaws and the Taylor-Chen-Kuszmaul model (TCK) for the intact rock are adopted to establish the corresponding dynamic damage constitutive model for the jointed rock mass under uniaxial compression. Finally, the effect law of the joint internal friction angle and the joint length on rock mass's dynamic mechanical property is examined with this model. The results show that the dynamic climax strength of the samples increases and decreases respectively with the increase of the joint internal friction and the joint length.
