Developing an Advanced Drive-by Bridge Inspection Technology

澳大利亚72%的桥梁是1976年之前建造的。目前桥梁检测多采用两年一次的目视检测，成本高、耗时长、主观性强。考虑到澳大利亚和世界各地大量存在缺陷的桥梁，以及道路管理部门有限的预算，该项目旨在通过先进的数据分析技术，仅基于经过桥梁的移动车辆的响应，开发一种低成本和健壮的桥梁监测框架，而不需要在桥梁上安装任何设备。该项目意义重大，因为它为可持续监测这种老化的基础设施开辟了新的方向，从而降低了维护成本，提高了安全性，延长了资产寿命。

72% of bridges in Australia were constructed before 1976. Currently bridges are inspected by biennial visual inspection which is expensive, time consuming and subjective. Considering the large number of defective bridges in Australia and around the world and the limited budget of road authorities, this project aims to develop a low-cost and robust bridge monitoring framework by advanced data analytics, solely based on the response of a moving vehicle passing over the bridge, with no equipment to be installed on the bridge. The project is significant because it opens a new direction for sustainable monitoring of such ageing infrastructure, consequently resulting in the lower costs of maintenance, enhanced safety and extended asset life.
