综合管线探测法在曹妃甸某港区探测中的应用

Application of Comprehensive Methods in Underground Pipeline Detection in a Port Area of Caofeidian

随着城镇场地的深入开发利用,地下管线的准确探查成为工程面临的首要难题。总结了各类管线探测技术的原理、适用条件以及具体操作方法,在此基础上采用直接法、电磁感应法、地质雷达法以及开挖验证等多种方式,综合应用于曹妃甸某港区地下管线探测,有效查明了地下管线的类型、数量、埋深等信息,并对探测过程中的存在的问题进行了深入剖析,提出了合理化的建议及相关量化指标,总结了一套地下管线探测方法。目前对于包含多种类型的复杂城市地下管线探测依然存在很多不确定性,相关研究成果偏少,研究成果可为类似管线探测项目提供参考。

With the indepth development and utilization of urban lands,the accurate locating of underground pipelines has become a primary problem to be resolved;Firstly,this paper summarizes the principles,applicable conditions and specific operation methods of various pipeline detection methods.On this basis,various methods such as the direct method,the electromagnetic induction,the ground penetrating radar methods and the excavation verification are comprehensively applied to detection of underground pipelines in a port area of Caofeidian.Methods of effectively identifying the type,quantity,buried depth and other information of underground pipelines,the existing problems in the detection process are analyzed,and reasonable suggestions and relevant quantitative indexes are proposed.A number of underground pipeline detection methods are summarized,which can provide reference for similar projects.
