摘要
在混沌理论的基础上,通过路基变形的历史数据记录,对路基变形进行分析,利用混沌时间序列的最大Lyapunov指数和全域法来预测路基的最终沉降.预测的结果显示,最大Lyapunov指数和全域法的预测可行,结果比较令人满意.同时与一些常规的预测方法进行比较,确定出路基的最终沉降,对路基进行卸载.
On the basis of the chaos theory, the road foundation＇s deformation is analyzed according to the historical data recorders. The road foundation＇s final sedimentation can be predicted by using the maximum Lyapunov exponent and the whole domain method of chaos time serial. The results are satisfactory, which show that the maximum Lyapunov exponent and the whole domain method are feasible. At the same time, compared with some normal prediction methods, the road foundation＇s final sedimentation is figured out.
