摘　　要：包气带的渗透性决定着水分在地表、土壤和地下之间的运输速度,是进行水资源评价的关键参数。为验证双环渗水法的效果,更好地研究包气带的渗透性。考虑不同的地貌单元和岩性的影响因素,开展3组双环法渗水试验进行分析研究。结果显示,双环渗水试验结果与现实贴近,并且其具备操作简单、价格低廉以及精度较高的特点。所得成果可为后续工作区研究水均衡、水库、坑地表水渗入量等基础数据提供参考。The permeability of vadose zone determines the transport speed of water between the surface,soil and underground,which is the key parameter for water resources evaluation.In order to verify the effect of double-ring seepage method and better study the permeability of vadose zone.Considering the influence factors of different geomorphic units and lithology,three groups of double-ring seepage tests were carried out for analysis and research.The results show that the double-ring seepage test results are close to reality,and it has the characteristics of simple operation,low price and high precision.The results can be used to study the basic data of water balance,reservoir and pit surface water infiltration in the follow-upworkarea.
