摘　　要：在盾构掘进过程中,由于施工或导向系统发生故障等原因导致盾构姿态错误时,必须采用人工测量盾构姿态的方法对导向系统进行修复。文中就人工姿态测量原理和计算方法进行了分析,提出了人工修复盾构姿态的方法并分析了方法预期达到的精度,同时结合工程实践分析了该方法对姿态的影响。When the shield posture error happens caused by the construction and the guidance system failure during the process of shield tunneling,it is needed to repair the guidance system by manual measurement of shield posture.By analyzing the principle and the calculation method of artificial attitude measurement, a new method of artificial restoration was proposed in the paper,and the accuracy of the method was analyzed.The influence to the attitude determination was also discussed according to engineering practice.
