GM(1,1)模型在深基坑变形预测中的应用

Application of GM(1,1) model in deformation prediction of deep foundation pit

本文主要以武汉某地铁车站的变形监测为例,结合前人对地铁车站变形监测较为成熟的研究内容,研究城市地铁车站变形监测技术、数据处理分析方法及数据预测模型,以便得出一些技术上的结论和工程应用上的方法。数据处理方法主要采用Excel表格方式进行整理,预测模型主要以灰色模型中的GM(1,1)模型为例,对该地铁车站变形监测的部分数据进行预测研究。

In this paper, the deformation monitoring of a subway station in Wuhan is taken as an example, and the deformation monitoring technology, data processing analysis method and data forecasting model of urban subway station are studied in combination with the research contents of the deformation monitoring of subway sta- tion in order to draw some technical The conclusions and engineering application of the method. The data pro- cessing method is mainly used to sort out the Excel table. The prediction model mainly uses the GM （ 1,1 ） model in the gray model as an example to forecast the partial data of the deformation monitoring of the subway station.
