Abstract
Recent increasing of redevelopment project causes construction of new buildings after demolition of old buildings. However, the researches have been largely confirmed to analysis of behaviour characteristics of existing subway tunnel due to adjacent excavation which constructing new building so far. Accordingly, The ${\bigcirc}{\bigcirc}$ Building which will be built after demolishing existing parking lot is selected as a subject of study. And the purpose of this study is to analyze the effects on existing subway tunnel due to loading and unloading caused by demolition of upper buildings. The numerical analysis was performed by using the MIDAS/GTS program. Two cases for the numerical analysis were analyzed. The one is considering demolition of old buildings and the other is not considering it. This study is to analyze the effect on existing subway tunnel caused by demolition of upper building by analyzing numerical analysis results for tunnel displacement and lining stress. It was analyzed that the effects of considering the demolition of old buildings are larger than those of no considering it.
