摘　　要：钻孔灌注桩的施工大部分是在水下进行的,其施工过程无法观察,成桩后也不能进行开挖验收。施工中的任何一个环节出问题,都将直接影响整个工程的质量和进度,甚至给投资者造成巨大经济损失和不良社会影响。必须防止在钻孔过程中及水下混凝土灌注过程中经常出出的施工质量问题的发生,保质、保量地完成桩基施工任务。文章根据混凝土灌注桩的工艺要求结合施工特点论述了凝土灌注桩的施工要点。Most of the construction of cast- in- place concrete pile is carried out in water, so the process can＇t be observed and can＇ t be checked by digging after finishing the pile. Every problem in the constructing process will affect directly the quality and the rate of progress of the entire engineering. Even it can cause enormous economic losses for the investor and bad social influ- ences. The frequent quality problems in the construction must be prevented in order to ensure both quality and quantity. The article discusses the main construction points according to the technological needs of cast - in - place concrete pile and the construction characteristics.
