Reducing the Risk of Reinforcement Corrosion in Concrete Structures and Stray Current Prevention in Metro Line

摘要：

The paper describes various models of steel corrosion caused by stray current in Metro line. Different model has different performance during service life stage. Their differences are presented by laboratory experiments. Furthermore, the paper describes different stray current collection ways. Extra stray current caused by extension construction has been analyzed. Key factors influenced on extra stray current are provided. Finally, reasonable extension construction ways has been provided to reduce stray current and reduce the risk of reinforcement corrosion in Concrete structures.
