摘　　要：从岩体不连续裂隙介质三轴蠕变试验结果，分析了开挖诱致岩体裂隙蠕滑全过程的基本特点。研究了裂隙起裂机制、蠕变扩展规律，讨论了岩体裂隙损伤断裂全过程与裂隙岩体蠕变全过程的耦合关系，并建立了相应的本构模型和分析模型，最后进行了算例分析。Based on the testing results of triaxial creep for jointed rock mass, the basic properties of complete procedure of excavation induced creep sliding are analysed. The study into initiating mechanism and creep developing law of joints is made. The coupling relationship of complete procedure is discussed between damage fracture and creep of jointed rock mass, and the corresponding constitutive model and analysing model are established. Finally, a computation is made for an example.
