摘要
高桩码头在使用过程中基桩容易出现损伤,目前,国内外对于有上部结构的基桩完整性检测方法的研究成果较少。本研究通过有限元数值模拟方法,确定高桩码头基桩现场检测时最佳的击振位置和信号接收位置,并利用小波分析方法对检测信号进行处理,以确定基桩的完整性。并结合已完成的相关研究成果,对高桩码头基桩完整性检测技术进行总结。
As for piled wharf,pile foundation is easily damaged in port operation.By now,a few research achievements are obtained for the integrity detection method of pile foundation with superstructures at home and abroad.Through finite element numerical simulation,the best knock and signal reception locations may be determined for piles foundation site-detection of piled wharf.Meanwhile,wavelet analysis is adopted to deal with the detected signals and determine the integrity of piles foundation.In addition,the integrity detection technique of piles foundation of piled wharf was summarized by combining with other research achievements obtained.
