摘　　要：通过简述现阶段常用基桩检测技术的检测原理、应用方向及自身特点,结合改扩建工程实例,明确基桩所处地质条件,优选适合的检测技术手段,应用高应变检测法、低应变检测法及静载试验等方法对基桩开展多维度检测工作,准确获知基桩承载力和完整性等相关要素,判断基桩是否满足工程需要,验证多种基桩检测技术的检测效果。This paper briefly describes the detection principle,application direction and characteristics of the common foundation pile detection technology at the present stage.Taking the example of an expansion project,the geological conditions of the founda-tion pile were defined,and appropriate detection technology was selected.Applying the high-strain dynamic testing,low-strain in-tegrity testing and static load test,multi-dimensional detection of the foundation pile was carried out,which produced the accu-rate bearing capacity and integrity of the foundation pile and other relevant factors.The research then determined whether the foundation pile met the project needs and verified the detection effect of various pile detection technologies.
