摘要
利用磁测法探测灌注桩钢筋笼长度在国内已经应用开展起来,但是在预应力管桩上的应用还属于空白。本文利用磁测法来探测预应力管桩的桩长,探讨利用磁测法的应用原理及其数据分析方法。理论分析及应用实例均表明,磁测法在探测预应力管桩桩长上的应用是有效、可行的,为判断预应力管桩长度提出了一种新的无损检测方法。
The magnetic method is widely used to detect reinforcement cage length of perfusion pile at home,but there is few research on the application of prestressed piles.In this paper,by using magnetic method to detect prestressed pile length,the application of the principle of magnetic method and its data analysis method have been evaluated.Theoretical analysis and application examples show that the application of magnetic method to the detection of the length of prestressed pile is effective and feasible.This paper presents a new nondestructive testing method to determine the length of prestress piles.
