| 摘 要： | 管桩中的铁磁性物质在地磁场中受到磁化而产生磁化强度,使管桩附近的磁场强度发生变化.把管桩中的铁磁性物质等效成直立磁性圆柱体,结合模型桩试验,研究了管桩外部的磁场特征,并且利用管桩外部的磁场特征确定了某居民小区住宅楼基础中管桩的长度.理论分析和工程应用均表明,磁测井法能够准确检测建(构)筑物下管桩的长度. |

| Abstract: | Ferromagnetism substances in the pipe pile will be magnetized under the excitation of geomagnetic field,which changes the magnetic field around the pipe pile.Ferromagnetism substances can be regarded as a right cylinder,and magnetic field characteristics around the pipe pile were analyzed on combination with model piles' tests.Lengths of pipe pile under buildings were detected by the magnetic logging principle.Application examples indicate that it is effective to detect the length of the pipe pile under buildings with the magnetic logging principle. |
| Keywords: | pipe pile magnetic logging principle magnetic anomaly length test |
