| Abstract: | The design height of the main tower of large span cable-stayed bridge is large. The construction of the inclined pylon with large dip angle is the difficulty and key. Based on the construction of main tower in Fuzhou railway Tongling Yangtze River Bridge, this paper introduces the tower construction by setting the active opposite transverse bracing to ensure construction safety and alignment of the tower structure. |
