Abstract

<p>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.</p>
