摘　　要：对西山水库工程来沙量计算分析,一是为水库除险加固提供依据,二是为无资料地区工程来沙量的计算提供参考。来沙总量包括悬移质和推移质。悬移质来沙量计算采用悬移质输沙模数图法和雨沙模型法两种方法,同时考虑人类活动对悬移质来沙量的影响;推移质计算采用系数法。根据水库运行以来的实际来沙情况,对计算结果进行合理性分析,最终采用雨沙模型法计算结果。The calculation and analysis of the sediment load of the Western Hills Reservoir Project provide a basis for the reinforcement of the reservoir and a reference for the calculation of the sediment load of the project in the area without data. The total sediment inflow includes suspended load and bed load. Suspended load sediment inflow was calculated by suspended load sediment transport modulus diagram method and rainfall sediment model method,taking into account the impact of human activities. The bed load was calculated by coefficient method. According to the actual sediment inflow situation since the operation of the reservoir,the rationality of the calculation results was analyzed,and the calculation results of the rain sediment model method were finally adopted.
