Abstract
In the construction of embankment with high water content cohesive soil, geotextile is often used in order to accelerate the consolidation of embankment In order to use geotextile efficiently, the effect of geotextile on the stability of embankment should be evaluated with high accuracy. In this paper, coupling analysis of limiting equilibrium state is conducted considering the effect of geotextile to accelerate consolidation, the effect of geotextile are examined. Main conclusion is as followings. 1) The relationship between stability of embankment and placing condition of geotextile is different according to the shape of embankment. 2) There is efficient placing condition of geotextile to stabilize embankment.
