A railway embankment route extending to 2 km was laid on normally consolidated clay in the West Gimhae Plain. This embankment was first built using the stage-construction technique, but longitudinal cracks suggesting arc sliding appeared on the surface of the embankment immediately after the first stage of its construction. As an alternative, the piled raft was installed on the failed embankment and then the remaining height of the embankment was raised. The behavior of the piled raft was monitored with different instruments during construction. This paper describes the monitoring results and analyses. The results show that if the pile group essentially exhibits the behavior of friction piles, the piled raft foundation performs well even in normally consolidated soft clay.
