摘　　要：针对传统地下管线定位技术危险系数高、测量精度低的缺陷,本文将惯性定位技术应用于非开挖深埋管线的探测中,通过对惯性陀螺仪探测系统的工作原理、工作流程、误差来源及精度分析进行研究,总结出一套适用于非开挖深埋管线的探测方法,并将其应用到相关的工程实例中。结果表明,惯性定位技术能够精确获取地下管线的空间位置信息,可以达到相关精度要求,为设计、迁改、施工等工作的顺利开展提供了重要依据和基础资料。In view of the defects of traditional underground pipeline positioning technology with high risk coefficient and low measurement accuracy,this paper applies inertial positioning technology to the detection of non-excavation deep buried pipelines,through the research on the working principle,workflow,error source and accuracy analysis of the inertial gyro detection system,a set of detection methods suitable for non-excavation deep buried pipelines is summarized and applied to relevant engineering examples.The results show that the inertial positioning technology can accurately obtain the spatial position information of the underground pipeline,which can meet the relevant accuracy requirements,and provides an important basis and basic data for the smooth development of design,alteration,construction and other work.
