Abstract
In the embankment for the slab track of Shinkansen, there are a lot of restrictions and it influences the construction cost for the improvement of the seismic effeciency and the decrease of maintenance. The expansion that material of the embankment is applied and the development of the method that rapid construction is possible were needed to construct more economical embankment. Then, we have developed pile slab track soil embankment that reinforced by geogrid against material with a lot of fine-grained soil etc, and supported concrete roadbed by piles with soil stabilization. We define the seismic behavior, response, and subsidence properties etc, from shaking table test and report the effect of material reinforced embankment and piles with soil stabilization.
