(北京波森特巖土工程有限公司，北京 102218)［摘要］低應變檢測和靜載試驗是兩種不同的樁基檢測方法，但卻能從不同角度反映樁基的施工質(zhì)量，因此結合兩種檢測方法能有效地分析施工過程中的缺陷。結合一實際工程，采用此方法分析了載體樁施工質(zhì)量不合格的原因，并提出了采用此方法對工程樁進行分類處理，最終進行處理后工程樁的質(zhì)量驗收。經(jīng)過檢測證明，該方法對處理載體與樁身結合不良的缺陷非常有效。［關鍵詞］載體樁；低應變檢測；靜載試驗；三擊貫入度；承載力Analysis and treatment of quality accident of ramcompacted pile with bearing base in an engineeringYang Qi an, Li Yupeng, Zhang Jianhong(Beijing Puissant Geotechinical Engineering Co., Ltd., Beijing 102218, China)Abstract:Although low strain testing and static load testing are two different testing methods, which can indicate the quality of construction in different ways. So with the combination of two testing methods, the defect of pile during construction can be analyzed. Based on a real engineering with the combination of low strain testing and static load testing, the reason of defect during construction was analyzed effectively. The method to classify and treat the pile was put forward, and it was also used to test the quality of pile after treatment. The testing indicates that the method is effective to treat the defect between shaft and bearing base.Keywords:ram-compacted pile with bearing base; low strain tes; static load test; penetration of three drive; bearing capacity國家科技支撐計劃課題(2006BAJ02B05)。作者簡介：楊啟安，碩士，高級工程師，Email:yangqian2000@126.com。參考文獻［1］JGJ94—2008建筑基樁檢測技術規(guī)范［S］.［2］曾國熙，劉金勵，等. 樁基工程手冊［M］.北京：中國建筑工業(yè)出版社，1995.
