Abstract

World widely, the occurrences of earthquakes have been increased recently. Speculating from cases of earthquakes in the world, it is reported that damages have been made underground structures like cut-and-cover tunnels, especially on the upper of tunnel with a shallow depth and the backfilled area adjacently by earthquakes. Earthquakes have a tendency to increase recently in Korea but it is deficient in seismic design criteria. In this study, Shaking table test on both soil and EPS blocks was performed to analyze the efficiency of the seismic performance of the cut-and-cover tunnels according to characteristic of backfill materials and embanking material. It turned out to be effective in improving the seismic performance according to analysis of strain and bending stress of tunnel by earthquakes.
