厦门海相软土地基沉管灌注桩施工质量异常原因分析
摘要:根据厦门市典型海相软土地区某工程沉管灌注桩桩身承载力和桩身完整性检测所发现的质量问题，结合沉管灌注桩施工工艺，分析得出厦门海相软土地区沉管灌注桩的施工质量问题主要为断桩和缩径，并对成因作出了分析，同时提出合理的处理建议。
Abstract:The abnormal qualities of vibro-pile of Xiamen typical marine soft soil foundation were detected respectively by the means of bearing capacity of pile testing and pile integrity testing. According to the characteristics of Xiamen's marine soft soil foundation and the construction technology of vibro-pile, the main influential factors of the quality for abnormal construction quality of vibro-pite were systemically analyzed. The results showed that the main quality problems of vibro-pile of Xiamen marine soft soil foundation were pile breaking and necking, and rational suggestions were taken for their solution.
