岩石破坏过程具有随机性。以弹簧、粘壶、试块质量3个元件组成岩石加载过程中的动力学模型,研究加载过程中的扰动对岩石破坏过程的影响。研究表明,当外载有合适的扰动幅度时,将出现混沌运动。
Random failure is a typical character of rock under extemal load. A model consisted of a spring, a cohesion kettle and a mass is given and the effect of load interruption is studied through catastrophe theory and chaotic theory. Through numerical simulation, a phenomenon is found in which chaotic behaviour will take place with a certain amplitude load.
