A study about rationalization of the design method for embankment using deep mixing method together with geogrid

Abstract

For construct of railway embankment on soft ground, we used deep mixing method together with geogrid to decrease settlement of the ground. Then, we need to understand the behavior of the embankment constructed by this method, caused by static load and dynamic load. So, we did dynamic loading test using two full-scale embankments on site. We will propose a rational method of design for embankment using deep mixing method together with geogrid, by analyzing these two tests. This paper introduces the result of these tests and the result of a numerical analysis.
