摘要:
为研究有侧倾偏位的钢管混凝土拱桥加固施工过程的稳定性,应用有限元程序建立了空间计算模型,对加固过程中的各种工况进行了屈曲分析,并分析了桥梁的失稳特征。结果表明:增加临时限位钢纵梁、在拱肋上加焊K字撑等措施很大程度地提高了施工过程中的稳定性,保证了桥梁加固的顺利进行及加固后桥梁结构的正常、安全运营; 该加固方案是有效可行的,可为同类型桥梁的加固设计与施工提供借鉴。
Abstract:
To research the stability of concrete-filled steel tubular(CFST)arch bridges with lateral displacement, and provide theory support to strengthening construction, the space calculated model was built to analyze the buckling and instability behavior of the bridge under various cases using finite element program. The results show that the strengthening measures, such as setting temporary fixing steel stringer and welding K-support bar on arch rib can greatly improve the stability of the bridges in all construction stages, and ensure the normal service after strengthening. The strengthening measures are effective and feasible, which can provide references for reinforcement design and construction of the same kind of bridges.
