현재 기존 지하구조물의 안정성에 영향을 미치는 신축구조물의 건설이 많아지므로 설계 및 시공 중 기술적으로 많은 문제점이 발생하고 있으며, 이러한 근접시공은 지하구조물의 중요도에 따라 지하구조물의 안정성과 신축구조물의 경제성이라는 두 사안이 절충 가능한 합리적인 설계 및 시공이 절실히 요구되고 있다. 지금까지의 지하구조물의 안정영역 및 지반거동에 관한 많은 연구가 이루어져 왔으나, 본 논문에서는 지하구조물의 상부에 구조물 건설에 따른 하중이 작용할 경우 지하구조물과 신축 지상구조물의 상호위치, 토피고 및 대상 지반조건이 지하구조물의 안정성에 미치는 영향 및 안정영역의 범위에 대하여 재평가하였다.

Nowadays, the construction of new ground structures, which can influence the stability of existing underground structures, is increasing. Consequently, many technical problems occur during the design and construction stage of the new structures. In constructing a neighboring structure, reasonable design and construction is strongly required to balance between the stability of the existing underground structures and the economy of construction of the new structure in terms of the importance of the existing underground structures. Many researches have been performed to estimate the safe region and behavior of underground structures. Constructing a new ground structure above the existing underground structure, external loads are to be applied to the existing underground structure. In this study, therefore, the stability and safe region of the existing underground structure was re-established with respect to the relative location of the new ground structure with the underground structure, the depth from surface to top of the underground structures, and ground conditions.
