Abstract

Generally, TBM specifications have been empirically designed by the know-hows of its manufacturers. Since they govern the excavation performance and the cost of TBMs, it is very crucial to reliably determine them in the design stage of TBMs. In this study, a database consisting of TBM data collected from a various kinds of TBM tunnel projects was built to propose the statistical correlations for estimating TBM main specifications. From the statistical analyses, TBM outer diameters are found to have a strong effect on the TBM specifications such as thrust, torque and cutterhead driving power, which are much more important than TBM types and ground conditions.

TBM의 제작 사양은 제작사들의 노하우에 의해 경험적으로 설계되고 있다. TBM 제작 사양은 TBM의 굴착성능과 가격을 좌우하기 때문에, TBM의 설계 단계에서 이를 데이터에 근거하여 결정하는 것이 매우 중요하다. 따라서 본 연구에서는 다양한 현장에서 사용된 TBM들의 정보를 수집하여 데이터베이스를 구축하였고, 이를 통계적으로 분석하여 TBM의 제작 사양을 추정하기 위한 상관관계들을 제시하고자 하였다. 분석 결과, TBM 최대 추력, 최대 토크, 공칭 토크 및 커터헤드 구동 동력과 같은 TBM의 최대 제작 용량은 지반조건이나 TBM의 형식보다는 TBM의 외경, 즉 TBM의 굴착단면적에 지배적인 영향을 받는 것으로 파악되었다.
