摘要：	Influence of engineering factors on the ground thermal regime of culvert is analyzed according to the finite element method and simplified model calculation in this paper. Two kinds of foundation of culvert affect the ground thermal regime differently. With great cement hydrate heat, direct and intense disturbance during construction, relatively high heat conduc tion coefficient, serious problem of seepage in the replacement and backfill soil around the foundation, the traditional deep buried concrete foundation generally doesn' t help the stability of culvert. While the improved shallow foundation with reinforced earth mat avoids the problem above and is easy to be implemented and benefits for the stability of culvert.
