摘　　要：介绍了盾构机姿态测量的人工测量方法和自动测量方法,通过实际工程数据分析比较这几种测量方法的精度,从精度、可操作性方面考虑选择自动测量方法进行施工测量,采用人工测量方法来检校自动测量的准确性。在保证测量精度的前提下,人工测量侧重于控制测量部分,自动测量使用于施工测量部分,两种方法有机结合,确保盾构隧道高精度贯通。This paper has presented several shield posture measurements such as manual measurement and automatic measurement methods which are commonly used in projects, it compares these measuring techniques by analyzing precision and convenience and chooses the best measurement method. Artificial methods which are used to measure the accuracy of measurements made more automatic. Ensuring the accuracy of measurement, automatic measurement is used in construct surveying and artificial measurement is used in control surveying. In practical project two measurements were implemented with great efficiency and speed.
