摘　　要：为解决克孜尔水库上游支流黑孜河的泥沙在鱼嘴附近淤积形成的拦沙底坎阻塞干流木扎提河的问题,提出了堤渠联合排沙试验方案,并通过试验确定了其在库区的布置方案。对方案实施前后汛期排沙资料进行的分析表明:若汛期库水位保持在1 135 m以下,入库流量小于750 m3/s,则能将支流黑孜河全年来沙量的85%排出库外;方案实现了干支流水沙运行路径分离的目的,有效地解决了黑孜河泥沙淤积对木扎提河的阻塞问题,基本实现了黑孜河库段的冲淤平衡,减缓了水库泥沙淤积速率。In order to solve the problem that block sand bottom formed around has achieved V - shape area of the Heizihe branch blocked the Muzat branch, the paper put forward that dam canal joint desihing experimental method and made sure the design of the reservoir area. The sedimentation data before and after flood season proves that the design has achieved the aim of the separation of water sand running path of branches. If the water level in the flood season keeps below 1 135 meter and water flow is less than 750 m^3/s can expel 85 percent of the sand in the Heizihe branch,resolves the problem of block Heizihe branch blocks the Muzat branch effectively and almost keeps the balance of silting of Heizihe branch, slow down the sediment deposition rate of the reservoir and expand the life span of the reservoir.
