摘要
探讨了该梁桥结构在实际运行时的可靠性、施工推行的高效性等重要问题.研究表明:简支钢板组合梁桥的承载性能的丧失前提是混凝土面板侧边碎裂且钢主梁产生塑性形变,若结构产生扩展性的裂缝,即判定结构破坏.相较于传统的小箱梁和预应力T梁,三主梁工字形钢混组合梁的实用价值和经济价值更高,施工期间对周围环境的影响也更小,还能克服气候条件的影响,极大地提高施工效率.
Abstract
The reliability of the beam bridge structure in actual operation and the high efficiency of construction are discussed.The results show that the loss of load-bearing performance of the simple supported steel composite beam bridge is based on the side fracture of the concrete panel and the plastic deformation of the steel main beam.If the structure has expanded cracks,it is considered that the structure is damaged.Compared with the traditional small box girder and prestressed T beam,the three main beams have higher practical value and economic value,less impact on the surrounding environment during construction,and can overcome the influence of climatic conditions,greatly improving the efficiency of construction.
