我国是桥梁大国,由于结构老化、运营管理以及建设质量等问题,近年来全国各地相继出现桥梁垮塌事故,造成了严重的人员伤亡和巨大的财产损失。为了保证既有桥梁的安全运营和尽可能延长其安全使用年限,对既有桥梁进行实时健康监测是非常必要的。由于桥梁健康监测系统投资、运营费用巨大和监测技术的不成熟,除少数特大型桥梁安装了监测系统9,9%以上的大、中、小跨径的桥梁都处于监测系统覆盖的盲区。文章主要探讨中小型桥梁健康监测系统的现状及近年来的进展,提出了一种基于智能传感器的中小型桥梁广域健康监测系统结构。

There are a large number of bridges in China.In recently years,many places have happened bridge collapse accident which caused by aging,bad management,construction quality,and other issues.Those failures caused serious casualties and huge property losses.In order to ensure the safe operation of existing bridges and prolong their life,install health monitoring system is necessary.Because the investment of building bridge health monitoring system and operating costs are very large,and the monitoring technology is not very maturationally,more than 99% of the total number of large,small and medium-sized bridge are not covered with health monitoring system except a few super-sized bridges.This paper discusses the status and recently progress of health monitoring system of small and Medium-sized bridge,brings a structure of wide-area health monitoring system based on smart sensor for small and medium bridges.
