| 摘 要： | 通过对损伤弹塑性模型和常规塑性模型两种有限元模型的计算分析得知，采用岩石力学参数计算的损伤有限元模型比采用岩体力学参数计算的常规有限元模型更能反映岩体的不连续性，且围岩位移的计算值怀实测吻合较好。

| Abstract: | The comparison and analysis of calculations with damage elastoplasticity finite element model and with conventional finite element model show that the damage finite element model that calculates with rock mechanical parameters are more precise than the conventional finite element model with rock body mechanical parameters employed in the calculation and the deformation values of wall rock obtained by means of the damage model correspond in a better way with in situ survey |
