| 摘 要： | 为做好山洪灾害治理中设计洪水计算工作,结合水利规划设计实践,以建始县4处小流域设计洪水为研究对象,分别采用流量途径、瞬时单位线法(降雨径流相关图)、瞬时单位线法(初损后损)、推理公式法和经验公式法等进行计算,并对相应成果进行了对比分析,最后推荐山洪灾害治理中小流域设计洪水采用瞬时单位线法(降雨径流相关图法)进行计算效果最佳。

| Abstract: | To calculate the designed flood in the control of mountain torrent disasters, we adopted the water conservancy planning and design practice.With the designed flood of four small basins in Jianshi County as the research objects, calculation was carried out by the flux path-way, instantaneous unit hydrograph (rainfall-runoff correlation curve), instantaneous unit hydrograph (initial losses and latter losses), ration-al formula method, experience formula method and so on.Corresponding results were comparatively analyzed.Finally, instantaneous unit hy-drograph (rainfall-runoff correlation curve) was recommended for the small basins design in the control of mountain torrent disasters.And its calculation effects were the optimal. |
