摘　　要：针对金狮子一级水电站的流量计算问题,通过收集和整理地理、气候、水文地质等基础数据,结合河流的流动特性,构建基于溃坝洪水不变水文率洪水流量模型。在汛期,该模型预测的流量为12.3 m^(3)/s,而实际测量结果为12.1 m^(3)/s,差异为0.2 m^(3)/s。尽管模型预测的流量和水位与实际测量结果存在一定的差异,但差异程度较小,说明该洪水流量模型在预测流量和水位方面具有一定的准确性和可靠性。In response to the flow calculation problem of the Jinshizi I Hydropower Station,a flood flow model based on dam break flood constant hydrological rate is constructed by collecting and organizing basic data such as geography,climate,hydrogeology,and combining with the flow characteristics of rivers.During the flood season,the model predicted a flow of 12.3 m^(3)/s,while the actual measurement was 12.1 m^(3)/s,with a difference of 0.2 m^(3)/s.Although there are certain differences between the predicted flow and water level of the model and the actual measurement results,the degree of difference is small,indicating that the flood flow model has a certain accuracy and reliability in predicting flow and water level.
