摘要高压旋喷桩广泛应用于我国建筑物的地基加固和防渗工程中，而传统的检测方法无法实现对其桩径有效且实时的测量。基于电磁感应效应，通过物理模拟试验研究不同桩径、探测方位、探测深度和附加易磁体体积条件下模型桩的电磁感应信号响应特征，并采用线性回归方法进一步分析检验。试验结果表明：电磁感应强度衰减速度随均匀掺入易磁材料的模型桩桩径的增大而减小；探测方位、探测深度不影响模型桩电磁感应信号响应；附加易磁体降低了桩体电阻率，加强了电磁感应效应；通过不同探测通道信号响应特征可以辨别桩体异常体方位。

Abstract：High pressure jet grouting piles are widely used in the foundation stabilization and anti-seepage engineering of buildings in China，while traditional detection methods cannot achieve effective and real-time measurement of pile diameters. Based on the electromagnetic induction effect，the electromagnetic induction signal response characteristics of the model piles under different conditions of pile diameter，detection orientation，detection depth and additional easy magnet volume were investigated by physical simulation tests，and further analyzed and tested by linear regression method. The test results indicate that the decay rate of electromagnetic induction intensity decreases with the increase of the diameter of the model pile uniformly doped with easy magnetic material；the detection orientation and detection depth do not affect the electromagnetic induction signal response of the model pile；the additional easy magnet reduces the pile resistivity and enhances the electromagnetic induction effect；the orientation of the pile anomaly can be identified by signal response characteristics of different detection channels.

Key words： foundation engineering high pressure jet grouting pile pile diameter detection electromagnetic induction linear regression analysis
