Abstract

As the construction of infrastructure using the underground tunnel in urban area have been rapidly increased, various accidents and collapses of tunnel including structure have been occurred in deep urban tunnelling. The concern and worry relating to the risk and safety of the tunnel during excavation is becoming the key issues in deep urban tunnelling. In this study, it was conducted for deep urban tunnel at GTX (Great Train Express) line which was located in Seoul metropolitan area to determine the risk characteristics for tunnel according to urban tunnelling. Also, it was reviewed the risk analysis and evaluation of the tunnel, shaft and station. And after a review of risk analysis and evaluation for risk register and hazard identification by using a risk matrix method, safety management of the tunnel according to excavation was evaluated to be secured. This study is expected to be applied as useful approach in deep urban tunnelling if you need to review the risk and safety management system of tunnel according to mitigation measures in complex urban tunnelling.

도심지에서의 교통인프라 개발이 활발해 지고, 대심도 지하터널을 이용한 도시의 기반시설 확충으로 인하여 도심지 구간에서 대심도 터널시공이 많이 이루어지고 있다. 이에 따라 대심도 터널시공으로 인한 터널안전 문제와 주변 지반 및 구조물의 안전 확보여부는 중요한 이슈가 되고 있으며, 터널시공에 앞서 대심도 터널공사에 따른 리스크를 분석하고 평가하여 리스크 관리를 반드시 수행하여야 한다. 본 연구에서는 대심도 터널과 도심지 터널이라는 특성을 반영하여 터널구간에 대하여 지반조사 자료, 설계 도서, 각종 사전 검토자료 및 시공계획 등을 바탕으로 수직구, 본선터널 및 대단면 터널 정거장 구간의 지하 안전성에 대한 주요 리스크를 분석하고 평가함으로서 수직구, 본선터널과 대단면 터널정거장 구간에 대한 안전리스크를 정량적으로 관리하고자 하였다. 본 연구는 도심지 대심도 터널공사에서 시공시 리스크와 안전 문제를 사전에 검토하는 경우 기본적인 기초 참고 자료로 활용될 수 있을 것으로 기대된다.
