摘　　要：采用自行设计的渗管反滤料渗透试验装置对新疆某引水工程反滤料进行渗透试验,研究在清水与浑水两种工况下四层滤料及河床料综合作用下的渗透特性。结果表明:清水试验反滤料渗水效果良好;浑水试验中反滤料渗透系数随着落淤厚度的增加而减小,渗管出水效果不明显,分析了影响反滤料"滤土"和"排水"作用的原因,为设计者提出合理的建议。The test device of infiltration pipe anti-filter penetration of self design was used to carry out anti filter penetration test for a water diversion project in Xinjiang so as to study the permeability characteristics in two conditions of clean water and muddy water under the comprehensive role of four filter and riverbed material. The results show that the anti-filter water seepage of clean water test has good effect; the permeability coefficient of filter material of muddy water test is reduced with the increase of falling slurry thickness. The effect of effluent water of infiltration pipe is not obvious. The paper analyzed the cause of impacting the role of filter soil and drain of anti-filter material,witch can put forward reasonable proposals for designers.
