摘　　要：运用三维直角坐标转换模型,解算盾构机轴线局部坐标系与实际三维空间坐标系两种坐标系之间的转换关系,然后利用转换关系求出铰接盾构机盾尾中心和铰接中心的坐标,再由铰接中心和得到的铰接千斤顶推进里程推求盾首中心的实际坐标,计算盾构机的姿态。该方法运用于地铁盾构的导向测量中,取得了令人满意的结果。The relation between the local coordinate system can be solved and the practical 3D coordinate sys- tem with the 3D datum transform model, and then by using the relation between the center coordinate of shield tail and link can be obtained, finally, the coordinate of the center of shield head can be solved based on the center of link and the distance of jack. The results show satisfactory when it is used in shield guiding in practice.
