摘　　要：挤土效应造成预制桩上浮是一个常见的问题,这会明显降低单桩承载力。采取适当的预防措施能有效消除或减少挤土效应,从而避免浮桩现象。The upward moving of precasting pile caused by soil squeezing is a common problem,and it can obviously decline the bearing capacity of single pile.Proper precaution measure can avoid the pile＇s upward moving by eliminating or decreasing soil squeezing effect effectively.

关 键 词：挤土效应 浮桩 承载力 孔隙水压力
