基于桥梁技术状况评定原理的系统评估程序化实现

Programmed realization of system assessment based on the principle of bridge technical status assessment

基于地铁五号线监测系统,通过时域与频域分析该系统中所采集数据,得出各个监测项目的动态阈值,并根据桥梁技术状况评定原理,采用JAVA语言进行评价系统的程序化实现。评估系统中单项评估可以较好的反映每项监测项目的变化情况,并通过动态阈值进行实时预警;综合评估可以直观的显示桥梁整体的健康状况,方便桥梁管理者了解桥梁实时状况并及时制定相应的养护维修策略。

Based on the monitoring system of Metro Line 5,the dynamic thresholds of each monitoring project are obtained by analyzing the data collected in the system in time and frequency domain,and the evaluation system is programmed in JAVA language according to the principle of bridge technical condition evaluation. The single evaluation in the system can better reflect the changes of each monitoring project and carry out real-time warning through dynamic threshold. The comprehensive evaluation can intuitively display the overall health status of the bridge,so as to facilitate bridge managers to understand the real-time status of the bridge and formulate corresponding maintenance strategies in time.
