S274.3; [目的]利用浑水波涌灌提高浑水灌溉地区水资源利用率,促进农业发展.[方法]在现有浑水波涌灌技术研究基础上,针对我国北方缺水现状及黄河流域河流泥沙量高等特点,通过浑水波涌灌间歇入渗试验,以清水间歇入渗为对照,设置4种不同浑水含沙率(3％、6％、9％、12％)以及4种不同颗粒级配组成(A、B、C、D)的浑水,共计14组试验,研究浑水波涌灌间歇入渗能力、浑水入渗减渗率等指标随入渗时间的变化规律.[结果]浑水波涌灌间歇入渗累积入渗量与入渗所需时间均符合Philip和Kostiakov入渗模型;在Kostiakov模型各拟合结果中,随着周期数的增加,拟合系数K和拟合指数α则均由大变小;在Philip入渗模型中,随着周期数的增加,拟合系数S与拟合系数A均由大变小.[结论]与清水间歇入渗相...
