Abstract

Recently, due to adjacent excavation work such as new buildings and common tunnel expansion concentrated around the urban railway, deformation of the underground box and tunnel structure of the urban railway built underground has occurred, and as a result, repair and reinforcement work is frequently carried. In addition, the subway is responsible for large-scale transportation, so ensuring the safety and drivability of underground structures is very important. Accordingly, an automated measurement system is being introduced to manage the safety of underground box structures. However, there is no analysis of structural damage vulnerabilities caused by subsidence or uplift of underground box structures. In this study, we aim to analyze damage vulnerabilities for safety monitoring of underground box structures. In addition, we intend to analyze major core monitoring locations by modeling underground box structures through numerical analysis. Therefore, we would like to suggest sensor installation locations and damage vulnerable areas for safety monitoring of underground box structures in the future.

최근 도시철도 주변으로 집중되는 신축건물 및 공동구 확장 등과 같은 인접굴착공사로 인해 지하에 건설된 도시철도 지하박스 및 터널구조물의 변형이 발생되고 이로인한 보수, 보강공사가 빈번하게 시행되고 있다. 또한 지하철은 대규모 수송을 담당하고 있어 지하구조물의 안전성 및 주행성에 대한 확보가 매우 중요하다. 이에 자동화계측 시스템을 도입하여 지하박스구조물에 대한 안전성을 관리하고 있다. 그러나 지하박스구조물의 침하 또는 융기 등에 의한 구조물 손상취약부에 대한 분석은 전무한 실정이다. 본 연구에서는 지하박스구조물의 안전성 모니터링을 위한 손상취약부를 분석하고자 한다. 또한 수치해석을 통해 지하박스구조물을 모델링하여 핵심 모니터링 위치를 분석하고자 한다. 따라서 향후 지하박스구조물의 안전성 모니터링을 위한 센서 설치 위치 및 손상 취약부를 제시하고자 한다.
