| Abstract: | This paper puts forth an observation and a calculation method about the horizontal displacement and torsion deformation of Yueyang Dongting Bridge's main suspended towers and strictly estimated the observation accuracy of deformation with the theory of the correlated adjustment. Therefore, it draws an important conclusion which is helpful to the deformation observation to come. |
