摘要
鉴于非开挖深埋地下管线一直是城市管线探测中的难题,本文针对小口径非开挖深埋地下管线提出了基于姿态测量原理的探测方法,推导了磁三分量及重力加速度三分量姿态定向公式以及曲线构建公式,对误差校正等进行了分析。并对基于此原理研制的仪器进行了探测试验,给出试验结果,评价了该方法的有效性及优缺点。
Since it is very difficult to detect deep underground pipelines accurately in cities, a method based on the attitude measurement to solve the problem is introduced in this paper. After figuring out the formulas to describe the tangent directions of discrete points on a spatial curve by three -component magnetic field and gravity field and analyzing the method of error correct, we made a instrument of the principle and did some experiments. From the results of tests, some conclusions are obtained and the advantages and disadvantages are presented.
