연약지반상 철도궤도 건설을 위한 성토지지말뚝 공법 개발

초록

Geosynthetic reinforced pile supported embankment for the rapid construction of railway concrete track in Korea is being developed by a national R&D project. Large scale model tests were carried out for the development of a design method. According to the developed design method, a test bed is being constructed in a real railway site and the behavior of embankment, piles, and geosynthetic are being monitored. This paper introduce the developing procedure and the highlighted results of the tests.
