摘　　要：西藏金河水电站根据地形特点采用跨流域引水发电模式。枢纽布置中考虑到引水防沙问题,采用“侧向取水、正向泄洪冲沙”及“表面排沙、中层取水、底层冲沙”的布置原则。首部枢纽组采用水库沉沙技术解决工程泥沙问题。为保证水库的泥沙库容,需进行不定期的冲沙及监测。According to the local topography characteristic of Jinhe hydropower s tation, the model of water transfer via inter-basin was adopted. In order to sol ve the problem of fetching water and the sand deposit,The principles of ″fetchi ng water lateral, flood discharging and sand sluicing from front″ and ″trashin g from Surface, fetching water at middle level, sand sluicing at bottom″ were i ntroduced. The technique of sand deposit in reservoir was adopted to solve the p roblem of sand in head building, it is necessary to aperiodic sluice sand and mo nitor to guarantee the storage for sand in reservoir.
