Abstract
Tohoku shinkansen is now being constructed on a very soft ground in the Hachinohe area. In this site, large settlement is predicted to occur on embankments under construction. We applied the geosynthetic sheet and soil cement column method to this site to decrease settlement of the ground. We tried two approaches to use this method; One is a dynamic loading test on the site, and the other is a numerical analysis of this site test.
This paper shows the numerical analysis of the dynamic loading test. We describe the normal stress and displacement of the ground, and tensions of geosynthetic sheets after dynamic loading.
