城市地下管线分类及物探探查方法应用研究

城市地下管线探查是一项综合且复杂的工程,特别是随着城市经济发展和科技的进步,新的材料和新的施工工艺给这项工作带来更多的难题。本文根据实际工作经验,按照不同的管线材料及施工工艺对地下管线进行分类,并对不同种类的管线探查物探方法应用进行了初步分析。对管线探测中比较困难的非金属管线和非开挖管线探查展开研究,认为在目前的技术条件下,探地雷达探查具有快速、准确、经济等优点。

The Classification of Urban Underground Pipelines and Research of Geophysical Detecting Method

It is a comprehensive project to detect urban underground pipelines. Especially with the economic development and technology progress, more and more new materials and construction crafts lead to more difficult problems to detect pipelines. This paper classifies the different pipelines according to the materials and construction crafts, and analyzes the different geophysical methods to detect the underground pipelines. Ground penetrating ra- dar is a good tool to detect non--metallic pipelines and trenchless pipelines in the current technical method.
