Analysis of Long-Term Durability Monitoring Data of High-Piled Wharf with Anode-Ladder Sensors Embedded in Concrete

The structural durability monitoring (SDM) system for a high-piled wharf in the Tianjin Port of China is devised and deployed with an anode ladder sensor, which provides means to monitor state steel corrosion wharf. In this project, anode-ladder sensors are installed on reinforced concrete components front platforms. After installation, data from sensor was collected 40 months. Based months, it proven that resistance will be significantly affected by change temperature, increase temperature cause drop resistance. Furthermore, set track beam platform shows current A1 A2 relative cathode exceeded 15 μA during four-month period, abnormal. main reason influence humidity. Therefore, current, voltage, resistance, should combined determine activation anode, cannot determined simply using value.
