摘要
工程安全状况的预分析是变形监测工作的重要组成部分。以济南轨道交通R2线济钢新村站基坑监测为例,基于灰色理论GM (1,1)模型,预测分析了变形趋势。结果表明,模型残差标准差<0.5 mm,误差区间<1.2 mm,多期监测的预测模拟分析结果中,7期监测数据的模型预测稳定性最高。
The pre-analysis of engineering safety is an important part of deformation monitoring.The authors take Jigangxincun station of Ji’nan rail transit R2 as a case study,using the GM( 1,1) model based on grey theory to predict the deformation trend.The results indicate that the standard deviations of model residual are less than 0.5 mm and the ranges of error are less than 1.2 mm.Of all the prediction modelling results in multi-stage monitoring,the stability of 7-stage monitoring data model is the highest.
