摘　　要：文章以福建莆田某房建项目中基桩为研究对象,对低应变法检测桩基质量状况进行了总结,并对检测数据处理及桩身完整性判别进行了研究,采用低应变现场检测的方法对桩基缺陷进行了分析。基于各向同性反射信号判断桩身缺陷的性质较为困难时,应判断病害的种类,并根据工程实际情况,采用挖掘法、岩心钻探法、声波透射法等手段加以确认。In this paper,the foundation pile of a housing construction project in Putian,Fujian Province is taken as the research object,the health status of the pile foundation detected by the low strain method is summarized,the detection data processing and pile integrity discrimination are studied,and the pile foundation defects are analyzed by the method of low strain field detection.It is difficult to judge the nature of pile defects based on isotropic reflection signals;It is necessary to determine the type of disease,and according to the actual situation of the project,the excavation method,core drilling method,acoustic transmission method and other means are used to confirm it.
