摘　　要：浑水渗流不同于清水渗流,在其渗流过程中,能够形成一层弱透水性的防渗层,减少渗漏水量。根据浑水渗流理论,提出采用引黄河浑水入库在库底形成淤积层来减少水库的渗漏。在分析了黄河浑水泥沙特点的基础上,研究黄河浑水引入平原水库形成的淤积层对库底渗漏的影响,并经室内试验研究得出渗漏量与淤积层的相关关系、不同水头对渗流量的影响关系,得出一定厚度的淤积层能够起到较好的防渗效果。将研究成果应用于平原水库库底防渗,经理论计算和工程应用评价,淤积层防渗效果能够满足设计要求,可为同类工程提供参考。During the process of the percolation, muddy water seepage can form a sediment deposit layer of weak hydraulic permeability to reduce the water leakage, which is different from the clear water seepage. According to the above muddy water seepage theory, the present study proposes that diversion of the muddy water from the Yellow River to the reservoir and then let the water to form the sediment deposit on the bottom to reduce leakage. Firstly, based on the analysis of characteristics of the silt of muddy Yellow River water, the research discusses the influence of the sediment deposit formed by the muddy Yellow River water on the leakage for the plain reservoir. Secondly, through the laboratory test, we get the correlation between the leakage and the sediment deposit formed by different water heads, and finally obtain the certain thickness of the deposit layer with the best impervious effect. Finally, the research results are applied to the seepage control of the plain reservoir; the theoretical calculation and the operation of the project evaluation show that the theory has satisfied effect and can be applied to other similar projects.
