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 cover thickness through modelling of heat transfer processes within the concrete and adjacent ground. A field. Central Research Institute of Building and Construction Co., MCC Group, Shenzhen, China 2., Shenzhen, China Distributed fiber optic sensing (DFOS) offers a transformative approach for monitoring geotechnical structures by providing continuous. Other fibre optic sensing methods, such as Fibre Bragg Gratings, have been shown to provide accurate and robust high-frequency measurements of pile installation. Measurements of a concrete driven pile load using conventional strain gauges and fiber optic distributed sensing were compared.
