28、频法。此法在实际工作中应用较少。直接法直接法有三种连接方式：单端连接、双端连接和远接地单端连接。三种连接方式都是将发射机电磁信号直接加到被查金属管线上。该法信号强，定位、定深精度高，易分清近距离管线，但金属管线必须有出露点，且需良好的接地条件。选用直接法时，无论那种连接方式，连接点必须接地良好，应将金属的绝缘层浔刮干净，接地电极尽量布设在垂直管线走向的方向上，距离大于1 0 倍埋设深度的地方，力尽量减小接地电阻。直接法严禁在易燃、易爆管道上使用。感应法通过发射机发射谐变电磁场，使地下金属管线产生感应电流，在其周围形成二次场。通过接收机在地面接收二次场，从而对地下管线进行搜查、定位。感应法分为磁

29、感应法和电偶极感应法。磁偶极感应法：分水平磁偶极子和垂直磁偶极子两种形式。水平磁偶极子：发射机呈直立状态，发射线圈面垂直地面，这是发射线圈与管合最强，可有效地突出地下管线异常，并可压制邻近管线的干扰。垂直磁偶极：发射机的发射线圈在管线正上方呈平卧状态，发射线圈面水文档编码:CZ3J3M4R8Q9 HT9P1U9T3U6 ZA7K5K1M9G5文档编码:CZ3J3M4R8Q9 HT9P1U9T3U6 ZA7K5K1M9G5文档编码:CZ3J3M4R8Q9 HT9P1U9T3U6 ZA7K5K1M9G5文档编码:CZ3J3M4R8Q9 HT9P1U9T3U6 ZA7K5K1M9G5文档编码:CZ3
