%X Interest on the instrumented pile load test using Distributed Fibre Optic Strain Sensor (DFOSS) has become a main discussion topic among engineers in the geotechnical field. Limitation of conventional instruments like Vibrating Wire Strain Gauge (VWSG) have led to the need of improvement in the sensing technology. DFOSS technology offers a continuous strain profile in a single sensing cable, and it differs from the conventional sensing technology, that only provides a point-wise measurement. Interpretation of the pile load results to establish concrete modulus and load transfer curves are critically analysed in this paper. This paper aims to propose the best methodology of unit shaft friction curve fitting method based on several points selection methods to provide a reliable and presentable of design parameter. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
