摘　　要：随着科学技术的不断进步,施工工艺的不断完善,地下隧道工程掘进长度不断刷新记录,因而对地下控制测量提出了更高的要求,尤其在一些为大科学装置施工的隧道中,其对隧道轴线偏差提出了更高的要求。以上海硬X射线自由电子激光装置项目工程为背景,详细阐述多闭合导线组在隧道施工过程中在地下平面控制测量中所取得的实践效果,为今后类似工程施工提供经验参考。With the continuous progress of science and technology,the continuous improvement of construction technology,the excavation length of underground tunnel engineering keeps setting new records,so the underground control survey has put forward higher requirements,especially in some tunnels constructed for large scientific installations,it puts forward higher requirements for tunnel axis deviation.Based on the project of Shanghai Hard X-ray free electron laser facility,this paper expounds in detail the practical effect of multi-closed traverse groups in underground plane control survey during tunnel construction,provide experience reference for similar engineering construction in the future.
