The embankment of JR-Tohkaidoh line beween Settsumotoyama and Sumiyoshi was destroyed by the earthquake of Hyogo south area on January 17th 1995. The line runs east and west on the embankment on the formar river lied north and south.
The embankment was supported mainly by the stone-piled retaining wall. The face of slope covered with concrete blocks was destroyed completely. Most of the retaining walls were clacked and, above all, some of them were devided in two pieces.
For the purpose of opening the two inside lines earlier, which was little damaged, and besides restoring the trucks of the two outside lines, the erection fixture was done. It obliged the embankment to be shut out by sheet pile. In order to improve this problem, we decided to take RRR method, which effected sufficiently also for this earthquake, and as the length to lay the reiforced segument could not be enough, we adopted radish-anchor method.
This report shows the guideline of our restoring this damaged embankment.
