现实中常常面临浑水渗流问题，而这方面的理论却并不多。浑水渗流具有随时间增长，渗流水中悬浮物不断沉积，导致地层渗透系数和整体渗透系数都不断变化的特点。浑水渗流是一个变水头非稳定渗流过程，尤其在黄河灌区，这类工程问题有长期浑水灌溉对土壤渗透性的影响，还有浑水在坝前淤积对绕坝渗流的影响。通过试验，测定了尾矿砂的颗粒级配曲线。开展了相同入渗水头，相同浑水含沙量，相同级配尾矿砂条件下浑水渗流试验研究。分析了渗流量随时间的变化情况以及浑水渗流对尾矿坝的影响。

During the experiments; we determined the grain grading curve of the last placer. The muddy water infiltration sand column pores experiment is under the condition of the same infiltration head, the same muddy sediment concentrations and using last placer of the same grading. We analyzes the head height change with time variation and the influence of the tailings dam which is caused by muddy water seepage.
