摘　　要：PHC桩具有施工速度快、单桩承载力高、工后沉降及不均匀沉降小、施工质量容易控制、单位承载力造价便宜等优点,目前在高速公路桥梁工程中尚未得到推广应用。从管桩填芯、桩长和桩间距等几个方面,对PHC管桩在桥梁工程中的应用进了系统研究,通过PHC管桩实体工程验证了研究成果的正确性。PHC pile has technical and economical advantages of convenient alternating construction, little post-eonstrnetion and differential settlements, high load capacity and savings of construction time and costs. However, it has not been popularized in bridge engineering. The PHC pile is studied by the filled-in core, length and spacing of piles. By the example of PHC pipe pile, the feasibility of the conclusion is validated.
