| Abstract: | The QingLing tunnel is the longest railway tunnel in china and takes the third place in the world at present. In this paper, the principle on which the first-order precise leveling is based. The leveling approach in the field work and some experiences of the application of new technology are introduced, and the problems existing during the alignment planning and design phase are pointed out. By the arrangement of the notes and the office calculation, the measurement result are excellent, and the reliabe surveying guarantee for this great tunnel engineering. |
