摘要
进一步完善了以往的时间序列分析方法,给出了相应的基本原理和建模分析步骤;分析去除确定性部分后的残差序列,提取其中的有规律性的成分作为预测时的补偿项,来形成模型;提出了信息加权的方法,给出了权重的量化标准,提高了建模和预测的精度;编制开发了时序分析程序。据此对现场隧道工程部分监测数据进行了时序分析研究,对相应预测结果进行了讨论。
In this paper, the time series analytical method was improved and related basic principle and modeling analytical steps were given. The regular part was extracted from the residual series received by model of observed data. A model is obtained by attaching the regular part as a supplementary item to the original model. The method of weight of information was put forward and quantitative norm of the weight was defined, the forecast precision was enhanced. Then, a related program was developed. Hereby, aiming at tunnel engineering in site, a study was carried out on monitoring data by time series analytical method and the related forecast result was discussed.
