| Abstract: | According to the Nanjing-Hangzhou high-speed railway requirement about elevation transferring for the long bridge with the second grade leveling in operation guide book,we conducted simulation experiments and field demonstration in different instruments and methods. Compare accuracy of elevation transferring by processing data under different situations,to apply the majority of the conclusions in the production process. |
