韭园沟流域相对稳定坝系防洪标准研究是在相对稳定坝系优化规划的基础上 ,通过建立坝系防洪标准研究数学模型 ,对不同洪水频率下坝系投资与垮坝损失进行计算、分析加以确定。研究表明 ,当韭园沟坝系中骨干坝取相同设计标准 ,坝系防洪标准为 10 0～ 2 0 0年一遇设计频率时是经济、合理的
The research on flood control standard of relatively stable dam system in Jiuyuangou watershed is based on the optimization plan of relatively stable dam system. By establishing mathematic model of flood control standard for dam system, the investment and dam failure of dam system under different flood frequency are calculated and analyzed determine. The research shows that when the backbone dam in Jiuyuan ditch dam takes the same design standard, the flood control standard of dam system is one case of design frequency in 10 0 ~ 200 years when it is economical and reasonable
