摘    要:根据白沙水库的水沙运动特点和库区地形条件,考虑了悬移质、推移质泥沙及水库异重流因素建立了一维全沙不平衡非耦合数学模型.利用1979年~1987年连续9年的库区淤积量资料对模型进行了验证.在设计来水来沙及水库调节条件下,应用所建模型预演了未来30年水库淤积对电厂取水口的影响.结果表明:白沙水库运行30年后,输水洞上层闸门不会被淤死,仍能正常输水,保证电厂的取水发电.

关 键 词:水库泥沙  异重流  数学模型  电厂取水

Abstract:Based on the analysis of sediment transport characters and the geomorphologic conditions of Baisha reservoir,a one dimensional nonequilibrium and uncoupled mathematical model of total sediment transport is established.The density flow is distinguished and calculated at the same time.The difinite difference method is used in the model.The model is verified with the data of sediment deposition and its distribution from 1979 to 1987,and used to predict the deposition in the furture 30 years and its effect on the water intake,showing that the upper gate of the water conveyance tunnel will not be silted up and can be used as usual up to the year of 2030.
Keywords:reservoir sedimentation  density flow  mathematical model  water intake of power plant
