About the Project
For a modern electric train traction system, the transmission of power is normally provided by an overhead wire or a conductor rail. The return circuit is usually through the running tracks which are connected to nearby substations. Stray current refers to the current which disperses directly to the ground through the return path. The leakage of stray current to surrounding reinforced concrete structures can lead to steel reinforcement corrosion and the subsequent disintegration of concrete.
The primary objective of this project is to develop a Corrosion Information Modelling (CIM) system which can be used for the prediction of the corrosion state in reinforced concrete segmental linings. The basis of the research is supported by the principle supervisor who has extensive experience in studying the electrochemical performance of steel reinforced concrete subjected to simulated stray direct current (DC) and alternating current (AC) interferences using experimental and analytical approaches [1-4].
