地铁工程盾构机(TBM)测量定向的研究

Study of Directional Surveying for TBM Excavation in Subway Construction

在地铁工程的盾构机测量定向中,最主要的是确定出盾构机内棱镜在无仰俯无旋转情况下的局部坐标,然后根据实测数据就可以计算出盾构机头部、中部、尾部中心的三维坐标,计算出它们的偏差从而达到控制盾构机姿态的目的。

In TBM directional surveying, it is the most important thing that how to determine the local coordinate of prisms in case of that there is no pitching and roiling. But, according to the surveying data, the 3-D coordinates of head, center and tail can be calculated and the ,deviation of them be found. Based on this information, how to control TBM excavation pose can be solved.
