APPLICATION OF CEMENT-MIXED GRAVEL REINFOERCED WITH GEOGRID TO THE CONSTRUCTION OF EMBANKMENT ON LIQUEFIABLE GROUND OR SOFT GROUND

Abstract

In recent years, cement-mixed gravel, crushed stone for mechanical stabilization with a little volume of cement, is often applied to soil structures allowing a limited degree of deformation. From laboratory tests or on-site tests, it was revealed that this material has sufficient strength and deformation characteristics against compression. Furthermore, this material exhibited a high resistance characteristic against bending moment by reinforcing this material with geogird. In this study, therefore, the applicability of this composite material as a bending member to the construction of embankment on liquefiable ground or soft ground was evaluated and a few typical case examples where the proposed method was applied for the construction of railway embankment were presented.
