摘　　要：渗透系数受到土层颗粒级配的影响。基于常州地区第5层粉土粉砂层渗透系数及特征粒径实测数据,建立土层渗透系数K与特征粒径之间的关系式。结果显示,该含水层渗透系数与土层等效控制粒径d60之间的关系式相关性高,对该含水层渗透系数的确定具有参考意义。The permeability coefficient is affected by the grain size. Based on the site survey of permeability coefficient and characteristic grain size of layer （5）（silt and silty sand） in Changzhou, the relationship between soil permeability coefficient K and the characteristic grain size is established. The experimental results show high correlation between permeability coefficient and critical equivalent grain size d6o, which is significantly meaningful to the determination of permeability coefficient.
