How Can a Fiber Optic Temperature Sensor Improve Tunnel Construction Safety?
Tunnel construction can be a major concern for engineers as it includes a higher risk. Whether for transportation, utilities, or mining, underground excavation often involves unpredictable soil behavior, high moisture levels, and thermal fluctuations. These conditions can impact structural integrity if not detected early. Safety during tunnel construction depends heavily on real-time monitoring of both mechanical and environmental changes. A Fiber Optic Temperature Sensor can track temperature variations continuously across the length of a tunnel. Unlike traditional point-based sensors, this technology uses a single optical fiber to measure thousands of temperature points in real time. This permits engineers to detect abnormal thermal activity, such as hot spots from mechanical friction, groundwater infiltration, or chemical reactions within concrete, before they escalate into structural threats. The fine spatial resolution enables early intervention to be visible or measurable th...
