本文以珠海某工程为载体,对珠海市横琴地区深厚海相淤泥地质条件下的冲孔灌注桩施工工艺进行了总结,与常规无护筒工艺进行了对比分析,并提出了双护筒灌注桩施工中应注意的问题和具体处理措施,为类似地质条件下的灌注桩施工提供一定的参考。 In this paper, a project of Zhuhai is taken as a carrier to summarize the construction process of perforated cast-in-place bored piles under the deep marine silt geological conditions in Hengqin area of ​​Zhuhai city. Compared with the conventional non-bored tubular craft, The problems that should be paid attention to in pile construction and the specific treatment measures provide some references for the construction of bored pile under similar geological conditions.
