摘　　要：小浪底水库坝前漏斗区的形成和发展,直接影响到枢纽建筑物的安全运行。为了保持塔前“门前清,”掌握坝前漏斗区的形成和发展,保证水库进入拦沙后期和正常运用期的正常运用,对坝前漏斗区进行了泥沙测验分析。结果表明:目前漏斗区范围内纵向坡度较缓,尚没有明显的漏斗形成,仅在坝前和塔前200m×1000m范围形成了漏斗雏形。The form and development of the funnel-shaped zone in the upstream of Xiaolangdi Reservoir will directly affect the safe operation of control structures. In order to keep ＂intake tower clean＂, to master the form and development of the upstream funnel-shaped and to guarantee the normal operation of reservoir entering later sand-intercepted stage and normal operation period, the sediment in the upstream funnel-shaped zone has been analyzed. The results showed that the funnel-shaped zone is gentle in longitudinal direction and do not still form obvious funnel and only has a embryonic form with a size of 200m×1000m.
