摘要
土工织物的孔径是反映其渗滤性能的重要参数,其测定方法有多种。采用显微镜法、泡点法、干筛法和湿筛法4种测试方法对不同工艺、不同面密度的9个样品进行孔径测试,并对4种方法的测定结果进行比较与分析,总结并讨论4种方法的优缺点及适用范围。
Pore sizes are important parameters for geotextile, due to its close relationship to the permeation property. It can be measured by a variety of methods currently. Microscopy, bubble-point, dry sieving and wet sieving methods were used to test the pore size of nine different samples with different areal densities by different technologies. The results obtained from the four methods were compared and analyzed. Then the merits and demerits of each method and their application ranges were summarized and discussed.
