桥梁挠度值在进行桥梁的安全性评定时是一项非常重要的指标.介绍了一种适合大跨度桥梁挠度测量的方法及其软件的开发原理.在一跨或者连续多跨桥梁上布置适当数量的倾角仪,通过倾角的测量,可算得试验跨桥梁各个断面的挠度值.通过工程实例来说明使用倾角仪法测量大跨度桥梁挠度的优点;通过对倾角仪法与光电挠度仪法测量的桥梁挠度值进行对比和分析,证明了倾角仪法计算得到的桥梁挠度值精度满足工程测量要求;最后对倾角仪法测量大跨度桥梁挠度所产生的误差进行了分析.结果表明,将该方法用于大跨度桥梁的挠度测量是切实可行的.

The deflection value of bridge is a very important index in the security assessment of bridges.First, a new method for the deflection measurement in long-span bridges and the theory on the development of relevant software were introduced.The deflections of different sections on experimental spans of bridge were calculated based on the angles of inclination which measured by a suitable quantity of inclinometers arranged on one span or several spans.Second, an engineering case was used to illustrate the excellence of deflection measurement with inclinometers in long-span bridges.By comparing the deflection values of the bridge from the inclinometers with those from the photoelectric flexometer, it is proved that the precision of the former meets the requirement of the engineering measurement.At last, the error of the deflection with inclinometers in long-span bridges was analyzed.The result shows that the new approach is feasible for the deflection measurement in long-span bridges.
