现行规范下箱涵的结构设计方法

箱涵属于超静定结构,因其刚度大、变形小、整体稳定性好、承载力要求低、可做多跨径连续框架等优点,广泛应用于公路和铁路,起到了良好的效果。鉴于此,运用现行规范的设计理论与计算方法进行箱涵结构设计,以期为同行提供参考和借鉴。

Structure Design Method of Box Culvert within Current Criterions

The box culvert belongs to statically indeterminate structure. Because it has such advantages as good rigidity, small deformation, good whole stability, low bearing capacity and could be used as multi-span con- tinuous framework, it is extensively applied to the highway and railway and has received good effect. Given this, this paper makes use of design theory and calculation method of current criterions to carry on a box culvert structure design, which can provide reference for peers.
