Abstract
Non-woven geotextile is often used as horizontal drainage for stabilizing embankment with high water content cohesive soil. In order to rationalize the design method, it is needed to establish stability analysis method, which is able to consider the effect of layout condition of horizontal drainage. In this paper, limit analysis method for stabilized clayey soil embankment using non-woven geotextile are proposed, the effect of layout condition of horizontal drainage is examined by conducting numerical analysis.
