摘　　要：桩身钢筋笼长度是影响桩身受力性能的一个重要因素,但桩基础施工完毕后,属于隐蔽工程,其长度是否符合设计要求却难以验证。针对桩基中钢筋笼长度检测难的问题,探索一种能定量或半定量检测桩体中钢筋笼的长度、且不需要进行破坏性开挖的无损检测技术是关键。本文简述了利用高密度电法测量系统进行钢筋笼长度的无损检测(充电法检测)的基本原理及其方法,并结合实际工程实例予以说明。Length of pile reinforcement cage is a key factor affecting the pile bearing performance.It is difficult,however,to verify whether its length complies with design requirements since the completion of pile foundation has made it concealed works.Thus a nondestructive quantitative or semiquantitative testing technology is essential to detect its length without destructive excavation.In this study,high density resistivity measurement system is put forward,including basic principles,methods and engineering applications for illustration.
