| 中文摘要: |
| 本文考虑锚固件在节理面上的局部行为，提出了一种新的加锚节理岩体流变模型，在此基础上推导了弹粘塑性本构关系并编制了三维有限元程序.实验室试验证实了模型的合理性.对某工程船闸闸首进行分析，得出了有关应力和变形及稳定性的认识。 |
| 英文摘要: |
| In this paper, a new rheological model of jointed rock mass reinforced by passive, fully-grouted bolt has been proposed. The model pays special attention to the bolt's behavior on joints. Based on the model, the elasto-viscoplastic constitutive equation is established in a 3-D FEM program. The model has been verified by the laboratory test and has been applied to the study of the upper gate bay of a navigation lock. |
