摘　　要：研制一种新型材料的管桩,将玄武岩纤维筋与预应力钢筋复合配筋做成复合配筋管桩,将这种新型管桩与普通管桩的抗弯性能进行对比试验。试验结果表明:BFRP筋能够较大幅度提高普通管桩的承载性能,新型管桩的开裂弯矩和极限弯矩均有明显的改善。A new type of pipe pile is developed,which combined basalt fiber reinforced bar and prestressed steel bar to make composite reinforcing pipe pile.The bending performance of the new pipe pile and the ordinary pipe pile are compared.The results show that the BFRP tendons can greatly improve the bearing capacity of ordinary pipe piles.The cracking moment and ultimate bending moment of the new pipe piles are obviously improved.
