摘　　要：覆土不锈钢波纹板涵(管)结构属于柔性结构,回填土与不锈钢波纹板结构之间具有很好的协同工作性。本文通过将土-结构相互作用分解为法向和切向行为,建立了覆土不锈钢波纹板涵的有限元模型,并考虑了不同摩擦系数的影响。研究结果表明,回填土与不锈钢波纹板之间的摩擦系数对不锈钢波纹板受到的法向和切向土压力均有影响;随着回填土厚度的增加,不锈钢波纹板涵受到的法向土压力将会逐渐趋于均匀分布。Corrugated stainless steel plate culverts are of flexible structures. There is better harmonious between backfill and corrugated stainless steel plates. In this paper, based on the soil-structure interaction behavior which is divided into normal action and the shear action, a finite element model of corrugated stainless steel plate culvert was set up, in which the friction factor between the corrugated stainless steel plate and the backfill was considered. The results presented that, both the normal and shear pressures were influenced by the friction factor, and the normal pressure distributed uniformly as the height of backfill increased.
