摘　　要：分析了土和普通混凝土的渗透试验方法,比较了流量法、渗水高度法、抗渗等级法和相对系数法,建议塑性混凝土按渗透系数大小选择抗渗试验方法。通过对沥青混凝土和黏性土渗透系数与孔隙率的关系分析,建议塑性混凝土在相对渗透系数计算公式中的孔隙率取0.06。Permeability test methods of soil and concrete were analyzed by means of comparing the flow method, seepage height method, impermeability grade way and relative coefficient method.It was recommended that the permeability test should be chosen accord- ing to permeability coefficient.Based on study on relationship of permeability coefficient and porosity ratio of asphalt concrete and cohe- sive soil, the porosity ratio in relative permeability coefficient formulas was recommended as 0.06 in plastic concrete.

关 键 词：塑性混凝土 抗渗试验 孔隙率
