| Abstract: | Long distance river-crossing leveling is an important job in the elevation control of the long-span bridge construction.Based on the influence analysis of river-crossing leveling,aimed lamp target for long distance river-crossing leveling is developed and used in the river-crossing leveling of Taizhou Yangtze river bridge construction.The experimental result shows that aimed lamp target suits the long distance river-crossing leveling and it is evident that the aimed lamp target can improve the survey precision and work efficiency. |
