摘要

对地埋箱形涵道和蛋形管道结构的设计计算，现行的方法是给定作用荷载值和分布，按结构力学方法求解。实际上作用于管道上荷载是随管土的相对刚度而变化的。为此，采用管土相互作用的Winkler模型和传递矩阵法，提出地埋箱形和蛋形管道结构计算的新方法。通过对箱形和蛋形管道与土相互作用的分析计算表明，即使是“刚性”的箱形管道也应考虑与土的相互作用。最后讨论了模型参数、埋深以及管道结构尺寸的变化对管道受力与变形的影响，说明了考虑地埋管道与土的相互作用，对地埋箱形和蛋形管道结构的设计计算才更符合实际。

Abstract

It is a traditional method that box-shaped and egg-shaped buried culverts are designed with given load. The method does not consider interaction between soil and culverts. But in fact

load acting on culverts is changed with relative stiffness of culvert and soil. So a new analytical method for egg-shaped and box-shaped buried culverts is advanced. Winkler model is used for the model of interaction between pipeline and soil commonly. Transfer matrix method is adopted. By the method

the internal force and distortion of pipeline is calculated and its importance is proved to consider soil retained to some stiffness pipe. Finally

it is discussed that model parameters

buried depth and pipe dimension affect to structural distortion and stress. Accordingly

it is more consistent with reality to design culverts by considering interaction between soil and buried culvert pipe.
