摘要
针对某广场在高强预应力管桩施工中出现大量浮桩的现象,研究了软土地基中管桩浮桩对桩侧阻、端阻和承载力的影响。通过对浮桩进行注浆和复打两种处理方法的对比研究表明,在软土地基中处理管桩浮桩应优先采用复打措施。文章研究成果对类似工程具有借鉴意义。
Aimed at the phenomena of prestressed concrete pipe piles floating, the influence of floating to shaft resistance, bottom resistance and boating capacity has been studied. Based on the contrast of grouting and re - beating of floating piles, the latter should be adopted in soft soil foundation. The conclusions offer references for similar engineering.
