초록

최근 터널 갱구부와 저토피 구간에 대한 환경 친화적인 터널공법에 대한 관심이 증가하고 있다. 콘크리트 슬래브를 이용한 반개착식 터널공법을 적용한 연구 및 시공사례가 증가하고 있으나, 하중조합 및 아치콘크리트의 단면에 대한 별도의 적용 기준이 없다. 따라서 본 연구에서는 반개착식 공법에 대한 기준을 제시하기 위하여 지반조건과, 터널 상부 지층 두께, 되메움 두께, 상부지반 지표면의 경사 각도를 변화시키는 등의 다양한 조건들에 대하여 수치해석을 수행하였다. 수치해석 결과들을 회귀분석법으로 분석하고, 유도된 회귀 분석식을 분류하고 정리하여 합리적이고, 경제적이며, 안전한 반개착식 터널 굴착 공법의 기준을 제안하고자 하였다.

Recently there has been increased interest for the portal and shallow tunnel for an eco-friendly tunneling method. Semi cut & cover tunnel excavation techniques applied to concrete slab and construction and a growing number of cases, but there is no load combinations and arch concrete cross section for the applicable standards. Therefore, in this study, ground conditions and tunnel overburden thickness, thickness of backfill, overburden surface slope angle changes to a variety of conditions in order to propose standards for the semi cut & cover method was performed numerical analysis. Regression analysis method to the analysis of the results of numerical analysis, and linear regression equations derived to classify and organize a rational, economical, and safe semi cut & cover tunneling method based proposed.
