无纺土工织物垂直渗透特性试验研究
Experimental study on the vertical permeability of nonwoven geotextiles
摘要
Abstract
Aseries of vertical permeability tests were conducted using non-woven geotextiles with unit area weights of 200,300,400 g/m2.The differences in the results of each test group were analyzed,and the influence of the unit area mass and the num-ber of layers of the samples on the test results was discussed.The results indicated that the flow rate was linearly related to the hydraulic head,decreasing with an increase in the number of sample layers.The permeability gradually decreased with an in-crease in unit area weight and the number of samplelayers.The vertical permeability coefficient values for various sample groups are within the same order of magnitude.For specimens with the same unit area weight,the vertical permeability coeffi-cient showed no obvious pattern with respect to the number of layers.With the same number of sample layers,the vertical per-meability coefficient decreases with an increase in unit area weight.关键词
