摘　　要：通过多次对涵洞变形产生原因的分析 ,认为原因是多方面的 ,而涵顶填土的作用较为突出 ,涵顶填土压力的计算 ,直接关系到结构设计。本文对铁路与公路桥涵设计规范有关填土荷载的计算作了介绍和对比 ,并提出相应的合理计算方法。Through analyses of the reasons which cause the deformation of culvert or tunnel several times, it is considered that there are many reasons, but the role of the soil filled on the top of culvert is more significant, which affects directly on the structural design. Based on the railway and highway bridge and tunnel design standards, the loading calculations of the soil filled on the top of culvert are introduced and compared, and the more reasonable calculating method has been proposed in this paper.
