Abstract

This paper reports on the results of an investigation into the feasibility of a fibre Bragg grating stress cell for use in a geotechnical environment. To increase the transverse sensitivity of the sensor, we encapsulated it in silicon rubber. Tests were performed in two types of singular grained compacted silica sands. The data obtained with the calibrated stress cell agreed well with the Boussinesq stress, and it is shows a fair degree of repeatability.
