摘要
论述了非线性动力学基本理论,将非线性动力学分析方法应用于岩石失稳预测中,建立了岩石失稳非线性动力学数学模型,用Lyapounov指数、Lyapounov信息维、Lyapounov信息熵、可预报时间尺度4个预测指标对岩石稳定性进行预测,并通过岩石单轴载荷声发射实验进行了验证。
This article elaborates the non -linear dynamics theory, applies the non - linear dynamics analysis method to forecast in the rock failure, establishes the non - linear dynamics mathematical model of rock failure, studies how touse the four forecasts targets, namely the Lyapounov index, Lyapounov information dimention, Lyapounov information entropy and the time criterion, to forecast the rock stability. The prediction method of rock failure has been validated in the rock acoustic emission experiment under Uniaxial Load.
