摘要
介绍了电磁感应法、磁梯度法、触探法探测管线的相关理论、探测效果及适用性。提出了运用磁梯度法和触探相结合的方法,对特大埋深非开挖管线精确定位。该方法在实际工程应用中取得了良好的效果。
This paper mainly introduced the theories and the applicability of electromagnetic detecting,magnetic gra- dient detecting and direct detecting, and proposed the method of combining magnetic gradients and direct detecting to precise positioning the deep underground pipeline. This method achieved good results in engineering applications.
