SEISMIC PERFORMANCE OF REINFORCED SOIL EMBANKMENT WITH PILE SLAB TRACK

In the embankment for the slab track of Shinkansen, there is a severe restriction of allowable settlement to preserve required performance. On the other hand, the construction method that expands the applicability of embankment material is needed to construct more economical embankment. Then we have developed the pile slab track soil embankment that is reinforced with geogrid against material with a lot of fine-grained soil, and can reduce settlement of concrete roadbed with soil foundation piles. We report the result of examination about the reinforcement effect of reinforcement material of embankment and soil foundation piles through shaking table tests.
