【摘要】 介绍了大跨度混凝土斜拉桥监测的现状、差动式传感器的工作原理,以及应变及温度监测方案的确定原则。作为工程实例,以某刚建成大跨度混凝土斜拉桥为背景,给出了大桥某天24小时的应变及温度监测结果,最后对差动式传感器的性能进行了分析。更多还原

【Abstract】 The situation of the monitoring of large span concrete cable stayed bridge and the work principle of the differential sensor firstly are introduced.Then,it discusses the monitoring scheme for strain and temperature.At last,a newly-built large span concrete cable stayed bridge is taken as an engineering example.In this example,the monitored datum of the strain and temperature within a day are provided,the performance of the differential sensor is analyzed as well.更多还原
