Retaining walls

It is very important to monitor the performance of a retaining wall to protect infrastructure such as roads or railways downstream of it. Geotechnical monitoring of retaining walls usually includes piezometers and IPI in-place inclinometers, while structural monitoring of retaining walls includes tiltmeters, anchor load cells and crack gauges.

What is retaining walls monitoring?

Retaining walls are commonly employed in landslides as a mitigation measure to stabilize and control slope movements.

Geotechnical and structural monitoring of retaining walls involves the continuous measurement and assessment of the performance and stability of the retaining wall structure. This is done to ensure that the retaining wall is functioning as intended and to detect any signs of potential failure or instability.

The geotechnical monitoring of retaining walls typically involves the following instruments: inclinometers, tiltmeters, piezometers, settlement gauges, load cells and strain gauges to measure the movement, pressure, deformation, and stress within the retaining wall and the surrounding soil or rock.

Monitoring of retaining walls is essential to ensure the safety and stability of the structures, as well as to mitigate potential risks and prevent failures. The data collected from the monitoring can help to inform decision-making and support ongoing maintenance and repair work.
