摘　　要：城市地下工程施工中测控技术及其精度是保证地下工程按设计要求准确贯通和工程质量的关键环节。结合南京地铁一号线工程和上海市某超长盾构隧道工程实践,探讨了地下工程测控技术的几个主要问题,采用GPS定位新技术、竖直导线定向法、加测精密陀螺方位角及棱镜法等方法进行了地下工程测控技术的研究,取得了令人满意的结果。工程实践表明,上述采用的测控技术和方法对于城市地下工程施工有实用价值。The technique and its accuracy of control surveying for underground engineering of city is the key to assuring the underground engineering penatration accuracy according to the design and the engineering quality demand . Based on practice of Nanjing subway No. 1 project and Shanhai super-long shield constructed tunnel project, several problems are loom large. Adopting the GPS new technique , vertical traverse orientation method and added measuring gyroscope azimuth angle to carry on the underground engineering obtained the satisfied result. The engineering practice indicates the above-mentioned control surveying technique for underground engineering of city is applicable and valuable.
