| 英文摘要 | Based on the theory of continuum damage mechanics, a modified Mohr-Coulomb failure criterion according to plastic damage evolution and the hydromechanical coupling is applied to analyse the excavation damage of Boom clay influenced by the evolution of pore pressure and plastic strain. Considering the actual case of construction of the connecting gallery of radioactive waste disposal in the deep Boom clay formation in Belgium, a nonlinear finite element damage model for simulating shield tunnelling is proposed to study the evolution of damage, pore pressure and permeability of the surrounding rock. The variations of damage and permeability around the tunnel with time are analysed in detail. The proposed model is able to effectively depict the main features of hydromechanical behaviours of Boom clay. Therefore, the present model can provide references for the distribution, degree and evolution of damage and fractures self-sealing process analysis of surrounding rock. |
