摘　　要：通过对深厚淤泥层某工程沉管桩基的施工中出现的质量事故，从挤土效应、孔隙水压、拨管速率、施工顺序、复打等方面进行分析。认为在此地质条件下，采用此桩型而工期又短，质量事故发生有一定的必然性，并就此提出了改进建议。This paper analyses a quality accident of pressed pipe cast-in-place pile foundation in deep thick muck stratum on such aspects of effcct of compactiong soil, pore water pressure, pipe pulling rate, consruction sequence and pile redrving. we also thinks it has some certainty to applying quality accident of this type of pile in the kind of geological conditions and make a suggestion for improving
