Simulation Analysis of the Construction Process of a Hybrid Girder Cable-Stayed Bridge with Profiled Towers

In order to study the mechanical state of the construction process of the hybrid girder cable-stayed bridge with profiled towers, this paper takes a bridge in Foshan as the research background, which is a 200 m main span hybrid girder cable-stayed bridge with 125 m high main towers and a span arrangement of (200 + 68 + 46) m. The research method of finite element simulation analysis is used to calculate the mechanical state of the main bridge structure under load. The results show that: the main tower under permanent action and combined action are maintained in a reasonable range, the structure under permanent action and combined action into the bridge state of the main beam stress, main beam deformation and cable force are located in a reasonable range, for the development of construction plans to provide effective reference value.
