Applications of Integrated Sensors in Monitoring Dams and Hydraulic Structures

Applications of Integrated Sensors in Monitoring Dams and Hydraulic Structures

Monitoring the structural integrity of dams and hydraulic structures is critical for ensuring their safety and functionality. Advanced sensor technologies play a pivotal role in collecting real-time data, identifying risks, and guiding maintenance efforts. Key sensors used in this domain include piezometers, pendulum tilt sensors, and temperature sensors, each addressing specific monitoring needs.

Piezometers for Monitoring Water Pressure

Piezometers are essential for measuring water pressure within and around dams. These sensors help track changes in pressure that might indicate seepage, foundation instability, or other hydraulic issues.

Application Example: At a major dam in Switzerland, piezometers were installed along the foundation and in the reservoir to monitor variations in water pressure during seasonal changes. The data enabled engineers to detect abnormal seepage patterns, facilitating early intervention and preventing potential structural compromises.

Pendulum Tilt Sensors for Detecting Structural Movements

Pendulum tilt sensors are widely used to monitor movements in large hydraulic structures. By detecting angular displacements, these sensors provide early warnings of shifts that could indicate foundation settlement or structural instability.

Application Example: In a hydroelectric dam in Brazil, pendulum tilt sensors were deployed to monitor the tilt of the dam’s concrete structure under varying water levels. Continuous data collection revealed gradual shifts in the upper sections, prompting reinforcement measures that ensured the dam’s long-term stability.

Temperature Sensors for Monitoring Thermal Variations in Concrete

Temperature sensors are crucial for tracking thermal fluctuations in concrete structures, which can lead to expansion, contraction, and cracking. These sensors help maintain the structural health of dams subjected to extreme temperature variations.

Application Example: At a dam in Canada, temperature sensors embedded in the concrete were used to monitor thermal stresses during winter. The insights from the data allowed the engineering team to implement temperature control measures, minimizing the risk of cracks and ensuring the dam’s durability.
