何家湾水库工程设计洪水分析计算

Analysis and Calculation of Design Flood of Hejiawan Reservoir Project

水库工程设计洪水分析计算对水库工程科学规划设计具有关键性的工程意义。为此,结合何家湾水库工程设计洪水分析计算典型案例展开分析研究。概述水库工程基本情况,完成设计暴雨分析计算;同时着重围绕水库坝址历史洪水调查、设计洪水计算(主要包括流域特征值、设计洪水及设计洪水过程线计算)和洪水成果合理性分析等方面实施何家湾水库工程设计洪水计算分析;并注重施工洪水与跨河(沟)建筑物洪水计算。为类似何家湾水库工程设计洪水分析计算实践提供借鉴参考。

The flood analysis and calculation of reservoir engineering design have the key engineering significance to the scientific planning and design of reservoir engineering.Therefore,combined with Hejiawan reservoir engineering design flood analysis and calculation,the analysis and study of the typical cases are conducted.Summarize the basic situation of the reservoir project,complete the analysis and calculation of the design rainstorm.At the same time,the design flood analysis of Hejiawan reservoir project is mainly carried out in the aspects of historical flood investigation,design flood calculation,which includes watershed characteristic value,design flood and design flood process line calculation,and rationality analysis of flood results.And pay attention to construction flood and cross river and ditch building flood calculation.It can provide a reference for the design flood analysis and calculation practice,which is similar to Hejiawan reservoir project.
