摘要
由于流量资料不足,龙门滩水库坝址设计洪水只能采用暴雨资料来推求。由于该水库流域内德化、凤洋、龙门滩等7个雨量站建成于不同年份,且每个测站的降雨资料并不连续,缺测年份较多,因此采用线性回归分析法建立线性回归方程式,进行插补延长得到各站连续57 a降雨资料。采用推理公式法、瞬时单位线法、地区综合法推算出龙门滩水库坝址设计洪水。
As the lack of flow materials, dam site design flood only could be calculated with precipitation data for Longmentan Reservoir. Because those 7 precipitation stations including Dehua, Fengyang, Lon^nentan, etc. were built in different years, and each station＇ s precipitation data were not continuous, there were many vacant years, linear regression analysis method was used and linear regression equations were built to interpo- late and extend the continuous precipitation data into 57 years. Reasoning formula method, instantaneous unit hydrograph method and regional com- prehensive method were used to calculate the dam site design flood of Longmentan Reservoir.
