Time Domain Reflectometry in Geotechnical Engineering

Time Domain Reflectometry (TDR) in geotechnical engineering is a technique used to assess the condition of soils and engineered materials by sending a quick electrical pulse along a wire or cable embedded in the ground. When the pulse encounters changes in material properties, such as moisture content or cracks, part of it reflects back. By measuring the time and strength of these reflections, engineers can identify variations and potential issues within the soil or structure, aiding in safety assessments, foundation design, and monitoring of complex geotechnical systems.
