Fibre optic sensing monitoring system for pile on slope

Monitoring system is very important in geotechnical works. In slope reinforced with pile, monitoring system is needed to monitor the displacement of the pile due to the slope instability. Therefore, this study will focus on a newly develop monitoring system using an optical fibre sensing technology...
