| 摘 要： | 针对工程实例中较复杂的桥梁结构采用梁格法进行计算分析,并采用近似分析方法——比拟板法进行验证。计算分析结果表明梁格法和比拟板法模型具有近似的刚度分布,计算结果相对差均在可接受的范围内,进一步说明了用梁格法计算复杂桥梁结构是可靠的,也证明实例工程设计的桥梁结构是安全可靠的。

| Abstract: | Aiming at more complicated practical bridge structure,beam grid method is adopted to make calculation and analysis and an approximate analysis method,the quasi-slab method is adopted to make verification.The calculation analysis results show that beam grid method and quasi-slab method have similar rigidity distribution and the relative differences of calculation results are both within the acceptable region.Complicated bridge structure is proved to be reliable by beam grid method and the bridge structure of practical project design is proved to be safe and dependable too. |
