Abstract
For construct of railway embankment on poor ground, we used deep mixing method together with geogrid to decrease settlement of ground. Then, we need to understand the behavior of the embankment constructed by this method using deep mixing method and geogrid, 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 one of these tests.
