Centrifugal Model Test on Deformation Control of Embankment and Surrounding Ground by Using Composite Ground Improvement

Abstract

In this paper, Dynamic centrifuge model tests were conducted to understand the effects of different cross-sections and unconfined compression strength of Composite ground improvement on the deformation of embankments and surrounding ground in response to Level-2 seismic motion. The result of dynamic centrifuge model experiment, we verified that Composite ground improvement can be expected to control the deformation of the surrounding ground against Level-2 seismic motion under the experimental conditions. However, the deformation control effect of the embankment depends on the cross section and strength of the shallow improvement.
