Construction monitoring analysis of the combination system bridge of cable-stayed bridge and shaped arch bridge
Abstrak
The combination system bridges of cable-stayed and shaped arch bridges feature innovative structures and complex force distributions, necessitating intricate construction processes. Monitoring these processes ensures that the bridge's stress state aligns with designed internal forces. Measured stress values on the main girder's edges align with theoretical trends but are slightly lower. Throughout construction, the middle span experiences compression, with maximum stresses of -5.1 MPa on both edges. Full support during construction minimizes the impact of stay cable and derrick tension on main girder stress. After support removal, compressive stress increases on the upper edge and decreases on the lower. The tower’s elevation is slightly above design, aiding in reducing prestress loss and deflection in later stages. At 16.5 m above the bridge girder, the tower’s left side experiences tension and the right compression, with a tensile stress of only 1.0 MPa, indicating sound design and effective construction control.
