摘　　要：根据规范,上游有控制性工程时,设计断面的洪水过程线应使用“地区组成法”推求。但关于地区组成法如何应用、设计断面的洪水过程线应如何叠加生成,规范中却未明确说明。文章通过塔岗水库除险加固工程中水文分析的实例,对地区组成法加以阐释。According to the specifications,when there are control projects upstream,the flood hydrograph of the design section should be calculated using the“regional composition method”.However,how to apply the regional composition method and how to superimpose and generate the flood hydrographs of the design section are not explicitly stated in the specifications.This paper explains the regional composition method through the examples of hydrological analysis in the danger control and reinforcement project of Tagang Reservoir.

关 键 词：地区组成法 设计频率洪水 相应洪水 洪水过程线 洪水叠加
