Dam Structural Health Monitoring Systems

Continuously read, record, and display data from multiple sensors across dam bodies, foundations, and abutments, enabling near real-time situational awareness.

Remote cellular transmission reduces site visits, accelerates decision-making, and supports automated alarms for threshold exceedance.

Provide high-precision measurement of horizontal displacement in dam foundations, main structures and intake towers, delivering early warning of structural movement.​

Long-term, highly repeatable readings support trend analysis and regulatory reporting for large gravity and arch dams.​

Track horizontal subsurface deformation and identify potential slip planes in embankments, slopes, and abutments.

Deep installations, including very high dams, enable continuous assessment of foundations and adjacent slope stability.​

Measure opening and closing of joints and fissures in dam faces, spillways, galleries, and tunnels, indicating stress redistribution or material deterioration.​

Multi-axis jointmeters capture complex three-dimensional movements at critical construction and lift joints.​

Monitor strain in reinforcing steel and mass concrete to assess load paths, thermal effects, and long-term ageing.​

Embedded sensors support validation of design assumptions and refinement of numerical models used in dam safety evaluations.​

Measure pore water pressures within foundations, embankments, and abutments to detect changes in seepage, uplift pressure, and internal erosion risk.​

When integrated with settlement and deformation data, pore pressure trends enhance understanding of overall dam performance under varying loading conditions.​

Detect and localize seepage in the dam volume. Localize crack in dam concrete and tunnels.

Monitor long-term concrete deformations due to load changes, concrete ageing and alkali-silica reaction (ASR).
