EFFECTS OF GROUND IMPROVEMENT AGAINST LIQUEFACTION BY CHEMICAL GROUTING METHOD UNDER EMBANKMENT

Abstract

In this study, we conducted a model test in 1g gravitation field and numerical analysis about seismic behavior of embankment on liquefaction ground. Test cases are non improved, and improved ground under an embankment by Chemical Grouting Method. From results, it is found that improved ground by this method has remarkable resistance against shear deformation after liquefaction, and seismic behavior of embankment can be simulated by effective stress analysis FLIP and LIQCA.
