磁测井法在灌注桩钢筋笼长度检测中的应用

The Application of Magnetic Logging Method to the Length Detection of Reinforcement Cage in Cast-in-situ pile

磁测井法是检测钢筋笼长度的一种高效可靠的方法,其原理是利用磁性体周围磁场变化的空间分布特征和规律,对钢筋笼长度进行检测。本文先介绍磁测井法的工作原理和构件完整性判定方法,最后结合具体工程实例说明其在灌注桩钢筋笼长度检测中的应用效果。

Magnetic logging method is an effective method to the length detection of reinforcement cage, the length of the reinforcement cage is measured by using the distribution of the magnetic flux density around the magnetic body. This article firstly introduces the work principle of magnetic logging methods, finally practical examples are given to show the application of this method.
