Research on the Technology of GFRP Bars and PC Strand Combined Supporting Piles by Experiment

Abstract:

GFRP bars and PC strand combination pile that is configuration GFRP bars in the compression zone of the general pile, in the tension zone configuration PC strand. Pile construction is completed and before the excavation, applied partially prestressed for the tension zone of PC strand, so that GFRP bars in tension, with the excavation pit, GFRP bars tendons pulling force gradually reduced; When the excavation to a certain depth, the second prestressed steel strand so until the excavation is completed. In summary, the technology features is GFRP bars, concrete piles, PC strand all in tension. This makes full use of the concrete compression performance, GFRP bars and PC strand tensile good performance characteristics.
