【摘要】 传感器优化布点问题是大桥监测系统的重要研究课题之一,针对在建的世界上最长的跨海大桥之一———杭州湾跨海大桥,对健康与安全监测系统中应变传感器的优化布点问题进行了研究,该文主要通过基于结构应变模态得到的广义应变能密度对桥梁应变传感器布点进行分析,并且综合考虑实际测试的情况,结合恒载作用下结构的应变情况,得出大桥应变传感器的布点,实现结构状态信息的最优采集。更多还原

【Abstract】 Monitoring system is very important to safe operation of large bridges.Optimal placement of sensors is an important part of the monitoring system.It has been studied in Hangzhou bay bridge,which is one of the longest bridge in the world.Placement of sensors is analyzed based on structural GSED-General Strain Energy Density,which comes from the structure strain mode.Considering the strain of dead force, we work out the placement of strain sensors for the southern sea-route bridge and the northern sea-route bridge of Hangzhou bay bridge.更多还原
