CSIR–Structural Engineering Research Centre (SERC) has introduced a modern, real-time system to monitor the safety of a key bridge structure in the Chennai Metro Rail Phase II project. This system has been installed on an important steel span near the Poonamallee Bypass.
The system uses advanced technology to check the condition of the structure continuously. Around 15 special sensors have been fixed on the span. These sensors measure how much the structure bends or moves when a train passes over it. In simple terms, they track how the track behaves under pressure to ensure it is safe.
All the data collected by these sensors is sent in real time to a secure online monitoring portal. This portal was developed at the Structural Health Monitoring Laboratory (SHML) of CSIR-SERC. Engineers and experts can use this system to closely watch the performance of the structure at any time.
According to a scientist involved in the project, the readings taken over the past 14 days show that the bending of the structure is within safe limits. This means the bridge is performing well and is safe for train operations.
This new system helps improve safety, allows early detection of any issues, and ensures smooth and reliable metro services for the public.
