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 coefifcient is affected by the grain size. Based on the site survey of permeability coefficient and characteristic grain size of layer⑤(silt and silty sand) in Changzhou, the relationship between soil permeability coefifcient K and the characteristic grain size is established. The experimental results show high correlation between permeability coefifcient and critical equivalent grain sized60, which is signiifcantly meaningful to the determination of permeability coefifcient.
