【摘要】 汶川特大地震给人民造成巨大的生命财产损失同时,灾区的交通公路桥梁等基础设施绝大多数被毁。文章首先对桥梁健康跟踪及灾后快速评估系统做了总体分析,然后针对监控量测及健康状态评价两子系统中的信号处理、信息处理、监测原理等方面所采用的现场总线技术、信号滤波、多主体协作和声发射等多项技术进行了简要分析。更多还原

【Abstract】 When the super earthquake of Wenchuan made demotic lives and wealth suffer serious damage,most of roadways and bridges also suffered huge damage or collapsed in the disaster area. According to these,this article firstly introduces and analyzes the total design for the bridge health tracking and fast evaluating system,then we briefly analyze several technologies such as field-bus technology,multi-agent cooperation,signal filtering method and acoustic emission based strategy in the respects of signal processing,information processing and damage diagnostic strategies between the monitoring test and status appraisal subsystems.更多还原
