近期，曾发生多起钢桁架桥斜杆腐蚀断裂的重大事故。因此，期望根据桥梁类型和结构特点，建立合理、高效的养护管理技术。本研究针对从钢桁架桥上切割下来的腐蚀的钢桁架桥节点板连接，利用激光测量设备详细测量了腐蚀形状，评估了节点板连接内外表面腐蚀的实际状态。
Notable accidents that the diagonal members of the steel truss bridges have broken due to the corrosion damage have occurred recently. Therefore it is expected to establish the rational and efficient maintenance management technique depending on the bridge types and structure characteristics. In this study, for the corroded gusset plate connection of the steel truss bridge which was cut out from the steel truss bridge, we measured the corrosion shape in detail using the laser measurement equipment, and evaluated the actual state of the surface corrosion outside and inside of the gusset plate connection.
