摘要
钻孔灌注桩采用后压浆施工工艺后,能大幅度的提高桩的承载能力,减少其下降,近年来已推广应用。某工程的钻孔灌注桩现场试验结果表明,后压浆工艺在灌注桩中运用效果良好,经济、社会效益显著。
New technology of pressure grouting around pile tip at sandy soil layer can largely improve pile bearing capacity and reduce its settlement. A site test proved a very good conomic benefit achieved as well.
