| Abstract: | In the construction of tied arch bridge, one of the key technologies lies in the control of the line shape joined. According to the control survey principle and specification, applying the three-dimensional coordinate method and revising the way rationally can guarantee the accordance of the installation of each joined section with the designed line shape. The project practice indicates this kind of control method is feasible and convenient to implement, and the precision of the data meets the demands. Therefore it has achieved the goal of monitoring and controlling line shape. |
