Abstract

Distributed fibre-optic strain sensing using BOTDR or BOTDA is an instrumentation technique that offers a spatially-continuous data. This is superior to more conventional discrete point-based sensors which provided limited monitoring information at pre-specified location points. The availability of a distributed strain regime offers a number of advantages when it comes to studying soil-structure interaction problems such as foundation piles. Distributed strain profiles from foundation piles are useful in understanding the actual behaviour of these structures and can provide important information to develop relevant computational finite element models. Axial pile strains can be integrated to obtain absolute pile displacements or can be differentiated to get pile shaft friction values. This paper describes the use of BOTDR/A in monitoring axially-loaded foundation piles and presents recent case studies in London. It also proposes an approach to develop finite-element load-transfer models for future analysis and design of foundation piles.
