基于极值原理的瞬时单位线法在洪峰求解中的应用研究
Research on the application of the Nash Unit Line method of flood peak calculation based on extreme value principle
【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.
【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.
【Key words】 Nash unit line; Flood peak; Blind mountain climbing method; Semi-divided method;
