OO상수도 밸브실은 하부 PILE 미설치로 인하여 부등침하가 발생하였으며, 이로 인해 벽체 이격, 상부슬래브 균열, 배 관 접속부 파손 등이 발생하였다. 부등침하로 인한 밸브실 및 배관의 안전성 확보여부를 구조해석을 통해 확인하고 보 수·보강 공법을 제시하고자 한다.

According to this research, the buoyancy force safety review of the buried water pipeline is carried out to determine the safety. In addition, it suggests ways to use as basic data for establishing future maintenance strategy.

According to this research, it was confirmed that safety coefficient is useful tool to rationally quantify structural deterioration of pipe. In addition, it could perform simple and rapid evaluation escaping from confinement by time and budget, and it can be utilized as a tool to set up policy for future water supply.
