| 中文摘要: |
| 工程中采用瞬时单位线法计算洪水时，洪峰均是从有限的计算节点上统计最大值作为洪峰，存在一定误差.当有较高精度要求时，不宜仅统计有限计算节点上的洪水最大值作为设计洪峰.采用瞎子爬山法和半分法计算洪峰流量，算法简洁明晰，计算开销有限，收敛速度快，是优良的计算方法，可供广大设计同行参考使用. |
| 英文摘要: |
| When the Nash Unit Line method is used to calculate the flood peak in a project，the maximum value of the flood peak is taken as the flood peak from the limited calculation node，and there is a certain error.When higher accuracy is required，it is not appropriate to count only the maximum flood value at the limited calculation node as the design flood peak.The blind mountain-climbing method and the semi-divided method are excellent methods for calculating flood peak flow，which are simple and clear，have limited calculation overhead and fast convergence speed，and can be used by many design colleagues for reference. |
