摘要

The quasi-three-dimensional calculation model of the underground engineering cavern was established. Two types of calculation parameters were adopted in this model. In the fivst approach, the corrected parameters were calculated by parameter inversion using the statistical characteristics of the geological parameters of the rock mass and the displacements data based on field monitoring. The second approach used numerical simulation to obtain the REV size of different rock zones, rock equivalent parameters and strength yield function considering random joints. The two parameters, were used in the simulation of the engineering excavation of the caverns. The estimated displacements of key points were determined from the calculation results. The opening displacements of the fracture fissures in surrounding rock were used to correct the numerical results from the empirical formula developed by previous scholars. The results showed that the corrected displacements of the key points coincided well with the monitored displacements. It proved that the calculation scheme based on the REV to study the equivalent parameters of a rock mass and the simulated yield function was realistic and convenient. Thys the rock mass was represented by an equivalent continuum material in the numerical calculation when the opening displacements of the surrounding rock fractures were included..
