| Abstract: | The control survey of sea-crossing leveling is a difficult point in the survey of modern major bridge engineering.In this paper,in the light of establishing of the control network for the construction leveling of Hangzhou Bay Sea-Crossing Bridge and on the basis of application of ATR technique,the specific methods for implementation of the ATR trigonometric leveling are presented.The analysis of the actual measurement data obtained from the leveling demonstrates that a good many precision indexes of the control survey using the ATR trigonometric leveling can satisfy the requirements of Grade 3 Leveling of the State. |
