본 논문에서는 쉴드 TBM 굴진 중 체적손실 산정과 관련한 기존 사례 및 정량적인 산정 방안에 대한문헌 분석을 수행하여 장비 형상과 운전 중 주요 기계데이터를 활용한 산정 방안을 도출하였다. 도출된 방안은기존 문헌에 보고된 토압식 및 이수식 TBM 굴진 사례 분석에 적용되었다. 전반적으로 계측 결과와 잘 부합하는것으로 나타났으며 일부 차이에 대한 분석을 실시하였다.
Abstract
Estimation of shield TBM tunnelling-induced volume loss is of great importance for ground settlement control. This study proposed a simple method for evaluation of volume loss during TBM tunnlling, which is able to take into account of shield machine configurations and main driving data in calculation. The method was applied to analyze the tunnelling cases with earth pressure balanced and slurry pressure balanced shiled TBM, and mostly, reasonable agreements with monitoring results were found. Additional discussions were made for some disagreements.
