浅析铁路桥涵小径流验证

通过对某铁路勘测地区进行小径流验证，进一步了解了影响小径流验证的各种因素，介绍了形态法、地方公式、推理单位线法和铁三院一法四种小径流验证方法及公式，经过对比分析最终确定了各段的小径流计算公式。

Initial analysis on the small runoff verification of the railway bridge and culvert

Based on verifying the small runoff in one railway exploration area,the author further finds out all factors of having influences on the verification of the small runoff,introduces four kinds of small runoff verification methods and formulas,such as the morphologic method,the local formula,the reasoning unit line method and the first method of the tesuzox institute,based on the comparison and the analysis,finally confirms the small runoff calculation formula of all sections.
