Abstract:

The chaotic characteristics of creep deformation of rock are studied based on rheological model method and test method; and the analysis of evolution process of chaotic behavior and the route to chaos as well as the occurrence condition of chaos are given. The engineering applications of the two methods and the theoretical and practical meanings of its parameters are also discussed. The results show that the development of rheological deformation of rock can be described as that: order-chaos(disorder)-order. Based on the property of development of creep deformation of rock has chaotic characteristics, the conclusion of controlling the stress level of rock creep system is the main method of avoiding chaos occurrence which is presented in the end.

Key words: rock creep, development of chaos, Logistic equation, rheological model, rheological experimentation
