摘　　要：为确保地铁车站明挖基坑施工安全和临近建筑物不受影响,灌注桩施工质量至关重要。地铁车站工程基坑支护灌注桩施工工序主要有钻孔、清孔、下钢筋笼、水下混凝土灌注等,每道施工工序工艺标准、技术参数符合设计规范要求,对易出现的质量偏差和常见的质量问题要采取针对性措施进行处理。In order to ensure the safety of the open-cut foundation pit construction of the subway station and the neighboring buildings are not affected,the quality of the cast-in-place pile construction is very important.The construction procedures of cast-in-place piles for foundation pit support of subway station engineering mainly include drilling,hole cleaning,lowering steel cage,underwater concrete pouring,etc.The process standards and technical parameters of each construction process meet the requirements of the design specifications,and targeted measures should be taken to deal with the easy quality deviations and common quality problems.
