摘　　要：莆田市城港大道木兰溪大桥的下部结构主桥桥墩有若干个直径为3.0m、2.5m的大直径钻孔灌注桩,浇注完毕后经检测发现个别桩身存在缺陷,严重影响该桥的质量,经研究采用钻孔注浆法进行处理,处理后缺陷桩达到了设计要求。There were many bored piles with large diameter of 3.0m and 2.5m in the substructure of piers in the main bridge located in the Mulan River bridge of the avenue of Chenggang. After pouring concrete we detected that some bored piles were so deficient that the quality of the bridge was seriously affected. We used the method of boring hole to pour grout to handle the problem. We found the piles with some defects accorded with the design demand through this process.
