Evaluation on effect of face wall in reinforced embankment

LIU Si-hong 1 ,CHEN Yue 2(1.Nagoya Institute of Technology,Nagoya466-8555,Japan;2.Suzhou Institute of Science and Technology,Suzhou215011,China)  
A number of soilbags are usually piled up to construct a face wall in the embankment reinforced with horizontal geotex-tiles.This face soilbag wall has a great effect on the stability of the reinforced embankment.In this paper,we propose d a method to evaluate the effect of the face soilbag wall.This method suggests two ways to deal with the face soilbag wall in the stability analysis for the reinforced embankment.One is to assume the face soilbag wall as a thin rigid wall;the other is to take an additional cohesion c of the soilbags,which is induced from the tension of the bag when the soilbag is subjected an external force,into account in the stability analysis.The safety factor of the reinforced embankment was chosen to be the smaller one of these two .A number of biaxial compression tests were performed on two-dimensional model soilbags and unconfined compression tests on real soilbags to illustrate the existence of the additional cohesion c in soilbags.Finally,an example of stability analysis for such reinforced embankment was presented.
