DFOS Embedded Ground Anchor Field Testing
A novel DFOS-embedded steel strand tendon ground anchor was developed with embedded fiber optic cables for strain measurement throughout the anchor cross-section. This unique cable configuration enables distributedstrain sensing (DSS) along the steel strand tendon, internal grout, and external grout during pull-out testing and long-term. A full-scale field test with four 60-ft (18.3m) ground anchors in mixed soil conditions was performed, with installation and pull-out… Read More »DFOS Embedded Ground Anchor Field Testing
