摘要: 以时间序列为基础,应用支持向量机建立岩体演化的非线性动力学模型,依据Lyapunov指数给出最长可预报时间,并通过函数拟合、变量代换将其化为标准的尖点突变模型,利用突变理论对其进行稳定性分析。结果表明,该模型预测效果理想,并具有良好的推广能力。Abstract: On the basis of displacement-time series, a nonlinear dynamics model is set up with support vector machine. The longest forecasting time is provided according to Lyapunov exponents and a standard cusp catastrophe model can be obtained through varibte substitution and function fitting. The results shows that this model can make satisfactory prediction results.
