摘　　要：将位置敏感器件（PSD）和其它元器件相组合，组成了介入式测量装置。通过使测量装置沿管道行进，获得管道内若干个测量点的方位，进而拟合得到地下管线的方位。该探测装置不受地下管线埋藏深度、密集程度和周围环境的影响，适用于内径为80～130mm、弯曲半径为50～1000m的管线。通过探测摆角的实例，得出实际测量值在水平方向上的测量误差为7．45％，竖直方向上的测量误差为1．07％。With combination of a Position Sensitive Device（PSD） and other components, a kind of detecting system in interpostion was developed for detecting underground pipeline. The system detected the orientaion data at different measuring sites to obtain the orientations of underground pipeline by walking along the pipeline,which could be used in those pipeline with inter diameter of 80-130 mm and bend diameter of 50-1 000 m ignoring the burying depth, the concentration of pipeline and other environments. The analyzing results of experiment show the relative error of the detecting method is 7.45% in horizontal orientation and 1.07% in vertical orientation.
