Geotechnical engineering directly impacts infrastructure safety, requiring precise mechanical parameters of soil and rock. Traditional measurement methods, such as electrical strain gauges and displacement transducers, face severe limitations in wet environments, limited space, and localized stress concentrations, often failing to capture full-field data.
To overcome these challenges, a leading university's School of Civil Engineering and Architecture adopted XTOP3D’s XTDIC 3D full-field strain measurement and analysis system for cylindrical geotechnical specimen compression tests. Utilizing advanced Digital Image Correlation (DIC) technology, the non-contact XTDIC system captured real-time 3D coordinates, displacement fields, and strain evolution during compression. It successfully visualized crack propagation and automatically generated comprehensive reports. Faculty feedback confirmed that XTOP3D drastically improved measurement accuracy and efficiency, providing invaluable data for optimizing geotechnical constitutive models and supporting tunnel, slope, and foundation engineering designs.
