INVESTIGATION OF SOME FACTORS ON CROSS-PLANE FLOW PERFORMANCE OF VARIOUS GEOTEXTILES

Abstract

The objective in this study is to consider a suitable geotextile filter to be hard to arise a clogging Chiba loam obtained from a field site and in-situ hydraulic gradient. This study was performed to focusing attention on a change of coefficient of permeability normal to plane on a kind of geotextile filter and ground condition. A series of constant head permeability test was performed to investigate a cross-plane flow performance of geotextile filter and clogging characteristic. Based on test results, it was found that the suitable geotextile filters to be hard to arise a clogging for Chiba loam are the GTXS-40 and GTXN-37.
