Corrosion environment monitoring was conducted on the structural members of a steel bridge truss in a marine environment. The corrosion depth measured on exposed monitoring steel plates and the galvanic corrosion current measured by Atmospheric Corrosion Monitoring sensors attached to structural members were used to evaluate the local corrosion environment of each type of structural member in the steel bridge truss. From the evaluation results, the corrosion environment of the horizontal structural member was found to be worse than those of the other members, indicating that the horizontal members should be the primary target for monitoring and maintenance efforts.

海洋环境下钢桁架桥局部结构腐蚀环境监测

在海洋环境中对钢桥桁架的结构构件进行腐蚀环境监测。在裸露的监测钢板上测得的腐蚀深度和由附着在结构构件上的“大气腐蚀监测”传感器测得的电腐蚀电流用于评估钢桥桁架中每种结构构件的局部腐蚀环境。根据评估结果，发现水平构件的腐蚀环境比其他构件的腐蚀环境差，这表明水平构件应成为监测和维护工作的主要目标。
