| Abstract: | Hangzhou Desheng highway viaduct is a continuous beam bridge that is across the Shanghai-Hangzhou Railway.It adopted an unusual construction method that one side using suspended wagon placing concrete,and the other side using scaffolding placing concrete.Moreover,the section constructions of both sides were not at the same time.Under the special condition,the construction methods and real time monitoring would guarantee the linear control of the main beam to meet with design requirements,which were introduced in this paper. |
