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．
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.
