摘　　要：根据试验资料,对Q1断面引水引沙情况及引水引沙过程进行分析,并研究河势变化、引水典型时段、间断引水过程、放淤闸位置及闸门运用方式等因素对引水引沙效果的影响。结果表明:试验引水引沙情况与大河的水沙条件、河势变化关系密切;做好水情预报工作,尽力避免试验工程出险,抓住有利、连续的引水时机,有效提高"淤粗排细"的试验效果。According to the data, this paper analyses the circumstance and process of diverting water and sand about Q1 cross - section, and researches the following factors how to influence on diverting water and sand： river regime change, typical interval of diverting water, discontinuous process of diverting water, the location of silt - releasing sluice and the service behavior of gate. The results show that, the circumstance of diverting water and sand of the test is extremely associated with water and sediment conditions and river regime change of the Yellow River. The test effect of ＂depositing coarse sand and discharging the free＂ is effectively improved through doing river forecasting work, trying to avoid the test works in danger and grasping the advantaged and continuous opportunity for diversion.
