| Abstract: | 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. |
