| Abstract: | The hanging baskets are the main equipments in the cantilever casting construction of large-scale prestressed concrete continuous rigid bridge and continuous girder bridge. The distortion control of hanging basket is very important to the construction control of continuous rigid frame bridge. Combining with an engineering case, this paper introduces the pre-load test of the hanging basket and analyses the change of deflection of the hanging basket, which will be meaningful to construction monitoring. |
