摘　　要：分析了预应力混凝土管桩施工中因挤土效应导致桩身上浮,承载力严重不足等问题,提出采用复压的方法对桩进行纠正,结果表明:桩顶标高达到了设计要求,复压效果良好,且有效降低了桩基的侧向位移,值得推广。The paper analyzes some problems in the pile floating and the insufficient loading capacity caused by the soil-squeezing effect in the prestressed concrete pipe pile construction, points out the rectification of the repressing, and proves by the result that the pile top elevation meet the design demands with better repressing effect, so it lowers the lateral displacement of the pile foundation and it can be further applied.

关 键 词：预应力管桩 挤土效应 复压法
