Recently distributed fiber optic sensing (DFOS) technologies provide a powerful tool for geotechnical monitoring by enabling distributed and automatic strain measurement along fiber optic (FO) cables.
In this study, distributed fibre optic sensing (DFOS) cables, embedded in a pile during concreting, are used to measure the changes in concrete curing temperature profile to infer concrete
This paper proposes a method that integrates fiber optic grating sensors, pressure sensors, servo motors, and a PLC control system to achieve dynamic tracking and monitoring of the
This study investigates the application of BOFDA distributed optical fiber sensing technology in static load testing of cast-in-place pile foundations to assess pile behavior and side
CSIC installed two fibre optic cables on the test pile, one for measuring strain and the other temperature. The two cables were installed side-by-side to enable the removal of any unrelated temperature effects.
The grout fills the cracks on the pile-soil interface, strengthens the mud cake around the pile shaft and tip, and increases the horizontal stress of the strata, thus improving the bearing
Discover the common fiber connector types. Learn the differences, uses, and best practices for SC, LC, ST, FC, MPO/MTP connectors.
The fiber optic cables were integrated into the pre-cast steel pipe piles before they were transported and installed off the coast of China in the East China Sea.
Presented in this paper is some first-hand fibre optic data collected from axial load tests on piles founded in dense to very dense sand, ranging from driven piles to screw displacement piles.
Several lessons were learnt from the application of distributed fibre optic sensors in piles, such as installation methods, influence of temperature, and performance of fibre optic...
The fibre optic cables were attached to a flexible pile that was embedded into the hollow core drilled through the entire length of the pile prior to demolition. The instrumented core was grouted to ensure
