| 摘 要： | 土工织物作为反滤材料在土石坝、堤防等工程中得到广泛应用，但土工织物的渗透特性测试到目前为止尚无合适的仪器。比较多家自制土工织物渗透仪的特点后，设计了一套土工织物渗透仪，结合某工程进行了多种型号的土工织物渗透试验，得到了土工织物渗透系数随法向应力变化的规律及织物对水泥的隔离性试验成果。

| Abstract: | Geotextures are widely used in earth rock dams and dikes as filter material,but the measurement of the permeability characteristics of geotextures remains a problem. A new permeameter for geotextures is designed on the basis of comparison of several permeameters for geotextures.Permeability tests of several kinds of geotextures have been done for a large project.The tests shows that the seepage through geotexture vares with the normal stress.The experiment of the cement insulating effect of geotexture is also done. |
