摘　　要：地下管线精细探测指在常规地下管线探测的基础上,针对工程建设中重点或疑难管线开展专项探查,采用专门的仪器和方法,通过高质量、高密度、高精度的探测,为城市规划设计施工提供更准确详细的地下管线现状结果。以杭州市余杭区城市地下市政基础设施普查项目为例,对精探方法在非金属燃气管线、大埋深长输管线和非开挖埋地电力线3种疑难管线探测中的应用效果进行了充分剖析,得出了有益结论。Fine detection of underground pipelines means that on the basis of conventional underground pipeline detection,special exploration is carried out for key pipelines or pipelines difficult to detect in engineering construction,and special instruments and methods are used to provide more accurate and detailed results of the status of underground pipelines for urban planning,design and construction through high-quality,high-density or high-precision detection.Non-metal gas pipelines,large buried pipelines and trenchless buried power lines are often difficult to detect in actual geophysical exploration work.Taking the survey project of urban underground municipal infrastructure in Yuhang district of Hangzhou as an example,this paper fully analyzes the application effect of fine exploration method in the detection of the above three difficult pipelines and finally draws some useful conclusions.
