| Abstract: | In order to assure the surveying accuracy of tunnel transfixion,the design and accuracy estimate of control survey in tunnel must be carried out before operation. In the present paper, the design schemes of horizontal and vertical control survey are described in detail. Meanwhile the corresponding formulas of accuracy estimate are presented. FinaLly, some approaches to enhancing the surveying accuracy are introduced based on the authors＇ experiences. |
