摘要: 为拓展钢波纹管的应用型式,运用大型有限元分析软件建立合理的力学有限元模型,对管拱型钢波纹管涵洞的受力变形进行了计算分析。运用有限元法分析得出管拱型钢波纹管涵洞土体受力变形规律。在建立的有限元模型中,通过施加公路-Ⅰ级荷载分析得出,填土高度对不同的拱顶角度的管拱型钢波纹管的周向等效应力、最大等效应力、横向位移、竖向位移的变化规律,确定了最优管型。对管拱型钢波纹管涵洞在公路工程中的发展、运用具有重要现实指导意义。

Abstract: In order to expand the application of corrugated steel tubular culvert, a computation analysis on the loading deformation of arch-shaped steel corrugated tubular culvert was carried out by a reasonable mechanical finite element model established by use of large-scaled finite element analysis software. The law of loading deformation of the arch-shaped steel corrugated tubular culvert was obtained by finite element analysis. Among the finite element models set up, the variation law of surrounding equivalent stress, maximum equivalent stress, lateral movement, vertical displacement of the arch-shaped steel corrugated tube under the forces of filling height acting on different vault radian were computed by imposing loads of rating I for highway. Thus the optimal tube shape was determined , which is practical and important and may guide the development and application of the arch-shaped steel corrugated tubular culvert.

Key words: highway engineering;arch-shaped corrugated steel tubular culvert, finite element, radian vault, filling height
