摘要
在流域水利规划或大中型水利枢纽的设计中,沙量估算与水量估算一样是一项重要的设计指标.它对工程安全,综合利用效益及各有关国民经济部门有直接影响.正确估算沙量为合理确定工程特征值和运用方式提供必要的依据.
The calculation of sediment discharge in design of hydraulic project is an important work. The calculation formula based on the incoming sediment coefficient equation is used in this paper,In which Rj,i is the incoming sediment coefficient. ( sediment concentration over discharge ) and Qj,i is discharge and Cj,i is characteristic of the incoming sediment, with j is section number and i is time, number.The characteristic Cj,i ie expressld by,( 2)In which Sk,i is characteristic of the incoming, sediment on feeder, P, K0,K1,K2…… Kk is hydrologic analog coefficient.The sediment discharage can be expressed by,( 3 )In which W.j,i is sediment discharage, t/s; ΔT is calculation time, s. Its accnracy is higher than that of the another method by using hyd-rologic analogue.
