도심지 대심도 터널 및 수직구 구간 지반안정성 평가를 위한 굴착영향범위 설정 사례 = A Case Study on the Establishment of an Excavation Impact Range for Evaluating the Ground Stability of Deep Tunnels and Vertical Shaft Sections in Urban Areas

다국어 초록 (Multilingual Abstract)

The setting of the target area for ground stability evaluation during ground excavation is categorized into theoretical and empirical estimation methods and numerical analysis methods. Generally, the applied theoretical and empirical estimation methods include those by Peck (1969), Caspe (1966), and Clough et al. (1990). The numerical analysis method comprehensively considered the current status of the task section (maximum excavation depth section, ground condition vulnerable section, etc.). It reflected the results of performing two and three-dimensional numerical analyses on the weakest section. Therefore, this study shows an example of setting the scope of influence when excavating the vertical and tunnel sections of a 000-line double-track private investment project through the above theoretical, empirical, and numerical analysis methods.
