Abstract
Geotextile or goecomposite drain sheets are used commonly for collecting and draining the seepage water in an embankment or the pore water in a cohesive soil with high moisture content. In these cases the combined hydraulic characteristics of the multi-layered structure depend on both the permeability of soil and the transmissivity in plane direction and the permittivity in cross-plane direction of a geodrain sheet.
In this study a laboratory two dimensional model test is conducted for a cohesive soil embankment in which a geotextile is placed. The effects of thickness of geotextile, overburden pressure and degree of compaction (i. e. soil density and permeability) on the hydraulic properties of the models are investigated and the results of tests and the interaction between the geotextile and the soil conditions are discussed.
