Abstract

The off-the Pacific Coast Earthquake Japan in 2011 resulted in serious damage on various structures and highlighted some new geotechnical engineering issues. This notified us that new ground improvement techniques are still required that can be applied under special execution condition to achieve retrofits ground improvement. As one of these techniques, this paper deals with a new cement-based grouting which is applied to gravel/boulder ground improvement. We first review conventional cement grouting, and introduce the new technique, then two experimental studies are shown. From these, the detail of the grouting practice is confirmed, and adaptability of the grouting is discussed based on the gravel/boulder size and plasticity of grouting material.
