Abstract
One of the important and fundamental functions of geotextiles placed in an embankment or a soil foundation is a transmissivity in its plane and a permittivity in perpendicular to its plane. The geotextile sheet can collect, infiltrate and drain water in the soil mass, for example, problematic cohesive soil embankment of high moisture content. Especially in order to promote drainage of seepage water and to accelerate a consolidation for increasing the strength of the earth materials, geotextiles sheets are embedded in a horizontal direction in the embankment or geotechnical structures.
In this study for the purpose of investigating fundamental hydraulic characteristics of geotextiles, laboratory model tests were conducted using geotextiles having different thickness. This effects of thickness of geotextile, overburden pressure, kinds of soil (volcanic cohesive soil of high natural moisture and pit sand), and head conditions on both transmissivity and permittivity are examined and discussed.
