Abstract

In this study, TBM selection methods to meet soil and site conditions were presented. Factors and excavation equipment affecting TBM selection by soil and environmental condition were selected and classified. Weights between equipment and influencing factors selected were calculated by applying the AHP (Analytic Hierarchy Process) method. The results of the analysis influence factors, Ground condition was a major factor in objective factors and strength was a major factor in the hard condition of criteria factors and water pressure was a major factor in the soft ground condition of criteria factors. In Environment condition, existence of adjacent structures was evaluated more important than existence of feasible site. Lastly, Adequacy was verified through the deduction of results that coincide with input equipment by applying derived weights to actual site conditions.

본 연구에서는 지반 및 현장조건을 고려한 TBM 선정방법을 제시하였다. 지반, 환경, 가격조건별로 TBM 선정에 영향을 미치는 인자와 굴착장비를 선정･분류 하였다. 선정된 영향인자와 장비 간 가중치를 AHP기법을 적용하여 산정하였다. 선정된 영향인자의 분석결과 기본요소에서는 지반조건이 가장 중요한 영향요소로 확인되었으며, 세부요소로서 암반조건에서는 강도, 토사지반조건에서는 수압이 가장 중요한 인자로 확인되었다. 주변 환경조건에서는 시공성에 영향을 줄 수 있는 주변구조물 인접여부가 중요한 인자로 확인되었다. 마지막으로 도출된 각 영향인자별 가중치를 토대로 굴착현장에 적용 가능한 TBM을 선정하고 도출결과와 실제 현장에 적용된 장비의 비교를 통하여 본 연구에서 제안하는 방법에 대한 검증이 이루어 졌다.
