摘　　要：第一部分,从非线性材料不可逆过程热力学的基本理论出发,阐明了岩石的时-温等效原理在客观上是存在的。第二部分将从理论和实验两个方面具体研究岩石时-温等效原理中的主曲线、主曲线中的移位因子及其参数的确定方法。Based on the theory of irreversible process thermodynamics in part I of this paper, non-linear thermodynamic analysis is engaged in , and non-linear stress-strain-temperature equations are established. Thus, general expression for time-temperature equivalent principle is theoretically obtained. And furthermore in part II, the equation of displacement facto in time-temperature equivalent principle is derived. At last, the parameters in the equation are determined, and the main curves for creep compliance and cohesive of three Gorges granite are obtained by a series of tests. As a result, it is proved that both deformation and strength performances obey the principle.
