| 摘 要： | 小流域公路桥涵设计洪水流量是确定小桥涵孔径、类型及建筑形式的主要依据。目前,我国有关小流域公路桥涵设计流量的计算方法仍然停留在20～30年前的水平。详细介绍了国内公路部门已有的小流域公路桥涵设计流量计算方法;然后对径流形成法和暴雨推理法的优缺点进行分析;在此基础上对已有方法进行改进,最终形成较为完善的小流域公路桥涵设计流量计算方法。

| Abstract: | Design flood discharge of highway bridges and culverts for small watershed is the important basis for the determination of pore size,types and architectural form.At present,the calculation method of design discharge for highway bridges and culverts in China is the same as tweenty year~thirty years before.The basis method of design discharge of highway department is introduced in details.Then,the advantages and disadvantages of runoff formation method and rainstorm inference method are analyzed.On the basis,the existing methods are improved so the perfect calculation method of design discharge for highway bridges and culverts is formed. |
