| 中文摘要: |
| 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。 |
| 英文摘要: |
| Based on f Corsac Bridge on the Sakhalin Island of Russia. The steel bridge in service under the ocean environment is affected by ocean, which leads to the steel corrosion and greater degree of damage and need research on structural reliability. Using the finite element model, the site of damage is simulated. According to the damage and corrosion grading, the ultimate bearing capacity of continuous composite steel bridge is analyzed and appraised. Advanced reconstruction proposals and future research directions are suggested. The result of this paper has certain theoretical meaning and application value in engineering practice. |
