Fiber Sensors used for Dynamic Pile testing

In a recent project carried out in the UK by ITM (Instrumentation, Testing & Monitoring) in cooperation with SMARTEC, a dynamic test on a pile was carried out.

Two concrete piles of 14m were tested, while instrumented with 4 SOFO sensors each.

SOFO Dynamic reading unit was used to perform both statnamic and dynamic tests. The aim of this project, was to validate the quality of SOFO Dynamic measurements for concrete pile monitoring. Tests on concrete pile are usually performed using traditional sensors such as accelerometer and theodolite to measure vertical displacements of the piles. The first aim of this project is to demonstrate that using optical fiber is a more suitable way to perform pile monitoring, by providing long-gauge readings all along the pile.

The results were very positive and will be published here in the future.
