针对山东引黄渠首口门泥沙测验中,由于受取样仪器的制约,仅能取到距河底0.1～0.3m以上的悬移质泥沙,给引黄渠首真实引沙量的评价带来一定偏差的问题,采用了引黄渠首闸前与闸后断面对比的实测方法进行研究。结论认为:漏测泥沙数量占闸前断面总沙量的7.5％～11.0％,漏测粒径大于0.025mm的有害泥沙为5％～8％。 In the sediment test of the leading edge of the Yellow River Diversion Canal in Shandong Province, due to the restriction of the sampling equipment, only the suspended sediment above 0.1 ~ 0.3m from the river bottom can be taken and the evaluation zone To a certain deviation of the problem, using the Yellow River Drainage Gate before the gate and gate section after the comparison of the measured method to study. The conclusion is that the amount of sediment that leaks and leaks is 7.5% ~ 11.0% of the total sediment before the gate, and the amount of harmful sediment whose size is less than 0.025mm is 5% ~ 8%.
