摘　　要：地下管线是城市的重要基础设施。非开挖地下管线竣工测量大多难以进行,精确测量更是缺少技术手段,因此这类管线的竣工资料非常缺乏。本文着重阐述和分析惯性定位技术探测非开挖地下管线的技术原理、施工方法、及技术特点。此外,还利用惯性定位仪的重复性测试和全站仪实测验证,证明了该仪器测得的数据准确、可靠。Underground pipeline is an important infrastructure of a city.Most of the completed surveys of trenchless underground pipelines are difficult to carry out,and precise surveys are lack of technical means,so the completion data of such pipelines are very scarce.This paper emphatically expounds and analyses the technical principle,construction method and technical characteristics of inertial positioning technology in detecting trenchless underground pipelines.In addition,the repeatability test of the inertial positioning instrument and the actual test of the total station testify that the data measured by the instrument are accurate and reliable.
