STUDY OF CHARACTER AND APPLICATION OF JOINTED ROCKMASS WITH NONLINEAR CREEP PROCEDURE
岩体裂隙非线性蠕变过程特性与应用研究

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.
