Focused on the clogging phenomenon of the geotextile tube bags which exists during the process of land reclamation,takeing the filtration system consisted of the tidal mud of Yangkou Port at Rudong County in Jiangsu Province,the nonwoven textiles,highly strengthened-woven textiles and plain woven textiles for an example,nine groups of gradient ratio test under three kinds of 6,8,11 average hydraulic gradient are carried out to measure the permeability coefficient of soil and fabric systems,phase soil infiltration capacity and gradient ratio.The results show that when the hydraulic gradient is 8and 11,and the gradient GR is less or equal to 3,the permeability coefficient of three geotextiles is larger and it has good filtration performance;besides,clogging phenomenon does not occur;when the hydraulic gradient is 6,the GR of the filtration system composed of soil and nonwoven textile is greater than 3,the permeability coefficient is quite small,and the clogging phenomenon occurs.The results of this experiment can provide a reference for similar projects.
