通过对主梁线形变化的实时监测及分析采集的监测数据,总结了主梁线形的长期变化规律,同时进一步对主梁线形的技术等级进行了评估。根据监测数据统计特征的相关评估理论,利用Matlab编程软件编制相关程序实现了监测数据的方便、快速处理。分析结果表明:基于统计特征的线形评估理论,能较好地实现对运营状态下的桥梁线形评估。
Through the monitoring of linear changes of the main girder and the monitoring data collected and analyzed, the long-term variation of the main girder linearity is summarized. Meanwhile, the technical grade of the main girder linearity is further evaluated. According to the related evaluation theory of the statistical characteristics of monitoring data, the Matlab program software is used to compile the relevant programs to realize the convenient and rapid processing of monitoring data. The analysis results show that the linear evaluation theory based on statistical features can well evaluate the linearity of bridges under operational conditions.
