摘　　要：本文以福清市某桩基工程为背景,采用声波透射法、抗压静载试验、钻芯法及高应变法等多种检测方法检测冲孔灌注桩在复杂地质条件下施工存在的质量问题,分析原因并采取加固措施,验证了加固处理后的效果,以期为冲孔灌注桩在类似地质条件下的应用提供有益参考。A pile foundation project in Fuqing area is taken as the background.Acoustic transmission method,compressive static load test,core drilling method,high strain method and other testing methods have been used to investigate the quality defects of construction of punching piles under complex geological conditions.The reasons and reinforcement measures are analyzed and the effect after reinforcement measures are verified to provide useful reference for the construction of punching piles in similar geological conditions.
