摘要
以实例为背景,为保障特种车辆通行,提出了在原桥上架设装配式公路钢桥的临时加固危桥方案。设计了钢桥和进出口的具体结构形式,采用数值模拟方法对不同结构形式钢桥的承载力和刚度进行计算和对比分析,计算结果和通车实况均验证了方案的可行性和合理性。
On the basis of construction practice, the project of erecting a prefabricated highway steel bridge on an existing bridge to temporarily strengthen the dangerous bridge to ensure the safe passage of special vehicles is proposed in the paper, with the specific structural forms of the steel bridge, and its inlet and outlet designed. The bearing capacities and rigidities of different structural styles are calculated, analyzed and compared by the software ANSYS, the result of the numerical simulation of which is compared with that of the practical passage of vehicles, and the project is found feasible and rational.
