Study on variation of pore structure of geotextiles effected by filtration with soils

A complete test procedure had been studied includ ing Modified Gradient R atio Test and Bubble Point Method in order to evaluate the anti-clogging poten ti al of a soil/geotextile system. The performance mechanism of soil particles and geotextile f abrics during filtration/drainage behavior had been revealed. The tests used in this study had been recommended with specific application conditions.
