摘要
本文介绍了一种磁测井原理检测钢筋笼长度的方法,通过磁感应强度或磁化率的变化来判断钢筋数量变化界面和钢筋笼长度,以此来推断预应力管桩桩长。
This paper introduces a method of magnetic loggi-ng principle to detect reinforcement cage length, to determine the Reinforcement quantity change interface and the length of reinforcing cage by the magnetic induction intensity or changi-ng magnetic susceptibility, in order to infer the prestressed co-ncrete tube pile length.
