摘　　要：介绍帕克西桥钻孔桩基础桩底压浆的施工,包括材料、设备及施工工艺。通过荷载试桩和O Cell试验,揭示了桩底压浆后桩端阻力和桩侧摩阻力成倍提高的现象,并对施工经验进行了总结。This paper presents the construction process of pile base grouting for bored pile foundations of Paksey Bridge, in which the selected materials, equipment and construction technology are covered. On the basis of the pile load tests and Osterberg-Cell tests, the paper reveals the phenomenon that the resistances at the pile tips and the frictional resistances at the pile sides are increased in times after the pile bases are grouted, and also summarizes the construction experiences acquired therefrom.
