摘　　要：温度效应是地铁桥梁健康监测系统数据预测的关键影响因素之一,结合某地铁高架桥梁已布设完成的健康检测系统,对监测数据与温度效应的回归分析进行验证,提出了一种温度效应从原始数据中分离的方法;通过将单因素ARMA模型与基于温度效应的ARMA模型预测结果进行对比分析,得出温度效应对健康监测系统的影响是不可忽略的结论。研究结论主要应用于地铁高架桥梁数据预测模型建立,同时也给其他结构数据预测模型建立提供了借鉴意义。Temperature effect is one of the key influencing factors of data prediction of subway bridge health monitoring system. This paper combines the health detection system that has been installed on a subway viaduct to verify the regression analysis of the monitoring data and the temperature effect. Based on this, a method to separate the temperature effect from the original data is proposed;by comparing the prediction results of the single-factor ARMA model and the ARMA model based on the temperature effect, it is concluded that the temperature effect on the health monitoring system cannot be ignored. The research conclusions are mainly applied to the establishment of data prediction models of subway viaducts, and also provide reference for the establishment of other structural data prediction models.
