摘　　要：在深层软土地基中预制方桩沉桩结束后,因土方开挖不当,将引起局部桩头偏移,而采取大直径钻孔灌注桩补桩,并利用桩底后压浆工艺,可提高钻孔灌注桩的单桩承载力,达到设计要求。After the settlement of plecast piles in deep soft soil foundetion,due to the inappropriate excavation of the slumps,some pile heads displace.So the big-diameter east-in-place piles are used,together with the late mud-jacking process,that can improve the single pile＇s hearing capacity of the east-in-place piles to meet the design need.

关 键 词：后压浆 钻孔灌注桩 承载力
