Abstract

Geocell that forms a structure with lateral binding force by confining infill material in the cells can reduce the stress on the subgrade layer. Therefore, it is expected to be used for the reduction of the stress of the load transferred to the road base. However, there are still many factors unknown about the strengthening mechanism. In this study, we conducted a loading test using a ground model made with EPS boards in order to identify the impact of Geocell on the changes to the stress distribution range. After the test, the deformation behavior of the EPS board was measured to determine the stress distribution range and to analyze the effect of Geocell installation on the ground.
