提出了利用原桥的重力式桥墩,架设装配式公路钢桥临时加固原有危桥,以保障特种车辆通行;运用ANSYS软件分析和计算了方案中钢桥的强度、稳定性和刚度,验证了方案的可行性;通车实况证明方案是合理的,也为装配式公路钢桥的架设和运用提供了成功的实例。
This paper proposes the use of the original bridge gravity piers and the erection of the prefabricated highway steel bridge to temporarily reinforce the original bridge in order to ensure the passage of special vehicles. The strength, stability and stiffness of the bridge are analyzed and calculated by ANSYS software. Feasibility of the program; the fact that the program is open to traffic proved to be reasonable, and it also provided a successful example for the erection and application of the fabricated steel bridge.
