摘　　要：延河龙安水库的功能以防洪为主,兼顾供水。为避免淹没建华寺镇,以“沐浴和仙仁桥并联两坝”方式,并考虑洪水期泥沙对水库淤积的影响,利用泥沙冲淤模型对拟定运用方式进行模拟。结果表明:较入库水沙长系列,洪水期泥沙对水库淤积影响较小,可采用入库水沙长系列确定水库合理运用方式。满足防洪目标的前提下,从库区累积淤积量、有效库容及兴利效益等多方面综合考虑,最终确定龙安水库合理运用方式为非汛期蓄水运用。该成果对以防洪为主高含沙水库合理运用方式的确定具有一定的借鉴意义。The method of "two dams of Muyu and Xian Renqiao in parallel" is adopted to avoid inundation of Jianshusi Town. Meanwhile, the influence of sediment on reservoir deposition is considered during flood period. The sediment transport model was used to simulate the proposed application modes. The results show the influence of hyper-concentrated flood on reservoir deposition is less compared with the long series of flow and sediment, so the rational operation mode of reservoir can be determined by using the long series of inflow water and sediment. Based on the flood control target, the reasonable operation mode of reservoir is determined to be the water storage operation in non-flood season, for the effective storage capacity and reservoir development benefit. The results have certain reference significance for the determination of the rational operation mode of reservoir with high sediment content flow which mainly focuses on flood control.
