磁测井法检测地下连续墙钢筋笼长度的应用分析

Application and Analysis of Magnetic well Method to Detect the Length of Reinforcement Cage of Slurry Wall

文中以福州市轨道交通6号线东调段某工程为例,采用磁测井法对该项目地下连续墙钢筋笼长度进行检测,经对比钻芯法试验,结果表明,磁测井法的检测结果准确性较高,用于推算地下连续墙墙体长度具有可行性,为轨道交通项目地下连续墙施工质量把控提供了一定的技术经验。

Taking a project of Dongtiao Section of Fuzhou Rail Transit Line 6 as an example,the magnetic logging method is used to test the length of the steel cage of the underground diaphragm wall of this project.The test results show that the magnetic logging method has high accuracy,and it is feasible to calculate the length of the underground diaphragm wall.Some technical experience is provided for the quality control of underground diaphragm wall construction in rail transit projects.
