摘要
１９９４年７月１９～２５日，由于特殊原因，黄河三门峡水库仅依靠电站坝段的机组及８＃钢管泄流，库水位较高（３１４～３１８ｍ），电站坝段８＃钢管出流中发生了“左侧为清水、右侧为浑水”的奇异异重流现象。认真分析研究此奇异现象，弄清８＃钢管出流中“为何浑清水不是上下层分布、而是左右侧分布？”、“浑清水分布形式是否在进入８＃钢管前已经形成？”、“若已形成，８＃钢管浑清水流程达１００ｍ之多，为何浑清水不在流程发生旋转或掺混？”等问题的原因，对深化水库异重流认识及解决电站排沙问题都具有重要意义。
The paper reports a special phenomenon in the Sanmenxia Reservoir. In 19 25 July, 1994, some water turbogenerators and releasing tube No. 8 of the reservoir were under operation at a rather higher water level(314～318m). It was discovered that a peculiar density current occurred in the tube No. 8, the clear water released in the left part of the tube and the muddy water was in the right part without any mixing, although the length of the releasing tube was over 100m. This special phenomenon may be caused by the topography in front of the tube, but its real reason should be further studied yet. \ \
