摘　　要：水下钻孔灌注桩被广泛应用于堤防等水下工程。由于其施工隐蔽、工艺复杂等特点,容易出现钢筋笼浮起、坍孔等施工事故,影响工程质量和进度,带来经济损失和安全隐患。文章通过总结江东堤防工程3合同段的工程实例经验,介绍了水下灌注桩的施工技术和要求等,以期指导今后工程实践。Under water bored pile is widely used in levee underwater engineering. Because of the characteristics of the construction hidden, complex process, prone to reinforcement cage floating, hole collapse and other accidents in construction, engineering quality and progress, bring economic loss and the potential safety hazard. Through engineering example to sum up the experience of Jiangdong dyke section of the 3 contract, this paper introduces the underwater cast-in-place pile construction technology and requirements, to guide the future engineering practice.
