The previous case studies have dealt with fibre optic (FO) sensors embedded in concrete or fixed to solid structures. Perhaps a greater challenge is the use of distributed fibre optic sensing (DFOS) in soils. One of the main issues is the degree of bonding between the FO cable and the soil and therefore the level of strain transfer. The following two case studies present instances in which DFOS was used on slopes to try to detect ground movement and/or locate slip surfaces. In both cases the FO cables were attached to secondary supports to enable their installation and ensure optimum strain transfer.
