【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.更多还原

【Abstract】 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.更多还原
