| 摘 要： | 以深圳市某大道顶管施工地下管线的探测成果为例,研究了在复杂场地条件下,探测地下管线的地球物理方法和技术,着重研究了电磁感应探测法.认为在复杂条件下,对钢质煤气管,应采用电磁感应探测法;对钢质或铁质给水管,应采用直接法;对电力管和电信管,应尽量采用夹钳法;对排水(管)渠等非金属材质管线,应采用地质雷达探测的方法.

| Abstract: | With the analyses of detection results of underground pipelines of some road in Shenzhen City, this paper discusses some geophysical detection methods and techniques of underground pipelines under complicated conditions, emphasizes on electromagnetic induction and geological radar. Detection case demonstrates that different underground pipelines should be detected by different kinds of detection methods and techniques with complicated conditions. Steel gas pipelines can be detected by electromagnetic induction. While steel or iron service pipelines should be detected by direct method. Electric power pipelines and telecom pipelines should be detected by pincers method. Nonmetal pipelines, including drainpipe and offtake, should be detected by geological radar. |
