摘　　要：在盾构法隧道施工过程中,盾构机姿态的准确性及稳定性对隧道的顺利贯通起着十分重要的作用。因此,需采用独立于盾构导向系统之外的其他测量方法,对盾构机姿态进行定期监控。基于盾构机本体独立坐标系的构建,结合工程实践,探析了空间距离交会法、两点直算法及空间坐标转换法在盾构姿态复测中的成果,验证了这3种检核方法的三维坐标分量差别较小、精度相当,均能满足对盾构机姿态复测的要求,可为盾构施工的测量人员提供参考。In shield tunnel construction,the accuracy and stability of shield machine posture are crucial for the successful completion of the tunnel.Independent measurement methods,separate from the shield guiding system,are required for regular monitoring of shield machine posture.By constructing an independent coordinate system for the shield machine and applying engineering practices,the space distance intersection method,two-point straight-line method,and space coordinate transformation method are analyzed for verifying shield posture.Results confirm that these three methods exhibit minimal differences in three-dimensional coordinate components and comparable accuracy,meeting the requirements for shield posture verification and providing valuable references for surveyors in shield construction.
