Laboratory model tests and mechanism of infiltration clogging effect of clayey soil

The gradation of clay, pore sizes of geotextiles, hydraulic gradient and soil compaction are preliminarily studied. According to the test results of clogging gradient, the clogging situations of geotextiles are analyzed under different apertures, clay contents, dry densities and hydraulic gradients. Through model tests, it may provide reference for future practice of geotextiles in different projects.
