Abstract

The application of TBM tunneling has been progressively increased since the first entrance into korea in 1985. In order to an apprehension and operation development of TBM method which has excellent boring in hard rock tunnel, this study has analyzed mutual relation of lose time and TBM boring from actual construction results TBM tunneling. This study compared this analyzed results with TBM tunnelling construction results of korea, america, japan, analyzed a primary factor of TBM boring effect and suggested operation development method from the analyzed results. accordingly this study can be used an index when contract apply TBM method to planning steps.

현재 TBM공법의 적용은 1985년 이래로 점진적으로 증가되고 있는 추세에 있다. 이 연구는 암반터널에서 탁월한 굴진실적을 갖고 있는 TBM공법의 이해와 운영발전을 위해서 TBM공법을 적용한 시공 사례의 시간손실과 TBM 굴진장의 상관관계를 분석하였다. 그리고 분석 결과를 기 분석된 국내, 미국, 일본의 현장 결과치와 비교 분석하여 TBM 굴진에 영향을 주는 요인을 분석하였고, 그 분석결과에 따른 운영개선방안을 제시하였다. 따라서 이 연구에서 제시한 개선방안은 향후 기본계획수립단계에서 TBM공법 적용 시 개략적인 지표로 활용할 수 있을 것으로 사료된다.
