| 摘 要： | 采用实测暴雨资料进行设计洪水复核,为龙脉水库除险方案和加固措施提供依据.复核中,通过对暴雨特性、暴雨频率分析,以设计点暴雨、设计雨型和设计面暴雨,采用扣损法进行产流复核分析,并进行时程分配,利用瞬时单位线法进行汇流复核计算,从而确定了水库除险加固设计洪水.通过与推理公式、经验公式和原设计成果比较分析,采用瞬时单位线法的洪水复核成果更为合理.

| Abstract: | The observed rainfall data are made use for the design flood review,to provide evidence for eliminating dangerous cases and reinforcement measures for Longmai reservoir.In the review process,through the analysis of storm characteristics and frequency,generated runoff are made checking in review process by using design point storm and rain type and surface storm according to deduction loss method research.And the distribution of schedule is made.Then concentration of runoff is made checking by the instantaneous unit hydrograph method in order to determine the design flood for removing danger and reinforcing the reservoir.With a comparative analysis of the reasoning formula,empirical formula and the original design results,it is shown that the flood review calculation results are more reasonable. |
