以俄罗斯萨哈林岛卡萨弗斯跨海大桥为研究对象,由于海洋环境的影响钢梁受到严重腐蚀,损伤程度较大,有必要进行相应的受力性能评估。利用有限元模型对损伤部位进行模拟,根据锈蚀损伤程度对钢混桥极限承载能力进行了分析和评估,结果表明,桥梁破损严重但承载能力符合规范标准,并提出了改造建议和未来的研究方向。其结果具有一定的理论意义和工程实践应用价值。
Taking the Sassafras Karossos Bridge across the Sea of Russia as the research object, due to the serious influence of the marine environment on the steel beams, the damage of the steel beams is serious, so it is necessary to evaluate the mechanical properties of the girders. The finite element model is used to simulate the damage site and the ultimate bearing capacity of the steel-concrete composite bridge is analyzed and evaluated according to the degree of corrosion damage. The results show that the bridge is damaged severely, but the bearing capacity meets the standard and proposes the suggestions of reform and future research directions . The result has a certain theoretical significance and engineering practice value.
