構造が異なるジオテキスタイルフィルターの垂直方向透水性に関する検討

The objective of this study is to consider a suitable geotextile filter to be hard to arise a clogging for fine-grained soils at a field site. This study was performed to focusing on a change of coefficient of permeability normal to plane on a kind of geotextile filter. A series of constant head permeability test on woven fabric geotextile filter was performed sandwiching in a geotextile filter between fine-grained geomaterial and gravel layer. Based on the test results and formally test results on non-woven geotextile filters, it was found that woven fabric geotextile filters in this study to be harder to arise a clogging than non-woven geotextile filters.
