| Abstract: | This paper presents a numerical analysis of the influence of new bored tunnel driven in close proximity on existing subway tunnels in soft soil.The objectives of this study are to propose a useful suggestion for new bored tunnel construction.The scope of the research is the behaviors of existing tunnels while the new bored tunnel is constructed. Analysis is performed using a three - dimensional finite element model,which takes into consideration the presence of the existing subway tunnels during the constmc... |
