Horizontal Displacement of GFRP Bars and PC Strand Combination of Technology Supporting Piles

GFRP bars and PC strand composite pile is a new supporting piles, according to the engineering field test and analysis of experimental data prove that there is a significant effect on the control aspects of the horizontal displacement of supporting piles. Principle energy method can calculate the horizontal displacement of pile foundation pit in theory, by comparing the size of the horizontal displacement of the supporting piles of ordinary reinforcement, to demonstrate the feasibility of using GFRP bars and PC strand combination of techniques to reduce the horizontal displacement of excavation, provide reference for future engineering practice.
