Abstract

This paper describes a case study of a bi-directional load test on a working pile located at limestone formation area. The test pile was instrumented with Distributed Fibre Optics Strain Sensors (DFOS) to measure the change in strain and to determine the pile shaft friction and end bearing. This paper highlights the advantages and limitations of DFOS in measuring the continuous strain profile of a test pile. Interpretation on the anomalies detected through the DFOS results is discussed. The paper aims to introduce to the industry, the superior information obtained using the innovative fibre optic technology for geotechnical testing and monitoring. © 2021 Southeast Asian Geotechnical Society.
