摘要
以深圳市地下管线探测工程为背景,介绍了电磁法三种观测系统,对不同情况下的平行双管线的电磁响应进行了分析,结果表明利用梯度法定位比其他方法更清晰准确,最后介绍了实际应用。
With the engineering of urban underground piplines exploration in Shenzhen city as background,three Surveying System of electromagnetic methods were introduced;the electromagnetic response of double-pipeline on different situations were discussed,it indicated that the positioning using gradient method was more clearly and more accurately than other methods.Finally,the actual application were introduced.
