| 摘 要： | 对含黏砂土进行3种试验方法的渗透试验，即变水头渗透试验、常水头渗透试验和一维垂直土柱积水入渗试验，探讨了含黏砂土的渗透系数与干密度之间的函数关系，试验结果表明渗透系数随干密度的增大而呈现指数函数形式的衰减。3种试验方法所得函数形式是一致的，说明3种方法测试含黏砂土的渗透特性都是可靠的。

| Abstract: | Permeability experiment of three experiment methods are carried out to containing clayey sand,which include chan- ging head seepage test, constant head seepage test and one dimensional vertical pole seeper infiltration test. The relationship between permeability coefficient and dry density is discussed. The experiment result indicates that permeability coefficient and dry density have a relationship of exponent function. Three experiment methods get the same function and prove that three methods of containing clayey sand permeability characteristic test are reliable. |
