Composites in Ground Engineering
Fibres are used extensively in the soilreinforcement industry [58].Polyesterbased soil reinforcement has been a commercial product for many years,competing successfully against steel alternatives [59].The polyester fibres are contained within a polyethylene sheath and are supplied in the form of flat strip (Paraweb).It is competitive in price,much easier to install,and much more durable.It has been used in a number of applications,including examples where the wall is in the tidal range (Fig.11),leading to alternate wetting and drying
Other composite applications include soil nailing using GFRP ,which is being pioneered in Germany,and the use of composite ground anchors in Paris,used as temporary supports for the basement of a multi-storey building.The composite anchors were placed where the ground was later going to be excavated by tunnel boring machines; steel anchors would have caused serious disruption to the cutting head of the machine.
Commercial Factors and the Future
The use of CFRP as externally bonded passive flexural reinforcement is a commercial success,due to the light weight of the material and the consequential savings in construction time.Similarly,the use of GFRP composites for complete structures is proving to be economic when there are access difficulties for building conventional heavy structures.The use of polyesters
as soil reinforcement is also commercially successful,due to their resistance to corrosion in potentially aggressive soil conditions.
