Abstract

The plan for major design-build projects of railway link among countries in gulf area (GCC) and freight rail construction is recently announced, but Korean companies have a hard time tendering due to special geotechnical condition in the Middle East. The major geotechnical risks during railway construction in the Middle East are related to ground improvement of soft Sabkha ground, wind-blown sand mitigation measure, dune sand compaction, and construction of large-scale cut and embankment. In this study, the characteristics of special geotechnical condition and potential geotechnical risks during railway construction in the Middle East are discussed on the basis of field observation, literature review, and field and laboratory test results.

Railway construction in the Middle East

Ground improvement of Sabkha ground

Wind-blown sand mitigation measure

Dune sand compaction

걸프지역 국가의 철도연계사업과 화물철도의 건설 등으로 인해 대형 철도사업의 발주가 이어지고 있지만, 중동지역 철도 시공 시 타 지역에서는 접하지 못한 특수한 지반조건으로 인한 리스크로 인하여 국내 업체들이 입찰에 어려움을 겪고 있다. 중동지역의 특수한 지반조건에 따른 주요 공학적 문제는 사브카 지반의 지반개량, 사막지역 모래바람 저감대책, 사막모래 다짐, 대규모 쌓기 및 깎기 등과 관련되어 있다. 본 논문에서는 현장조사 및 문헌조사, 현장시험 및 실내시험 결과 등을 토대로 중동지역에서 접할 수 있는 특수한 지반특성과 시공 상 리스크를 분석하고 대책을 논의하고자 한다.
