非线性时序分析模型在地下工程位移预报中的应用

Application of Non linear Time Serics Analysis Model to Displacement Forecasting in Underground Engineering

在现场采集大量数据的基础上，对支架位移建立了非线性时序分析模型ＳＥＴＡＲ（ｄ，ｌ；ｐ１，ｐ２）。用该模型对支架位移进行了拟合和预报，取得了较为满意的结果。

On the basis of a lot of data collected in the field, non linear time series analysis model has been set up for the displacements of metal supports. It has shown good effectiveness to apply it to model and forecast the displacements,and this is usefull to forcecast the stability of support structure by applying displacement back analysis.
