As the construction of urban tunnel close to building increased obviously, it is difficult to ensure the safety of the upper buildings and tunnel structure in construction. By using finite element software, this article makes numerical simulation analysis for new tunnels through the foundation of high-rise building. Considering many factors as the level of surrounding rock, tunnel size, building foundation forms, building height, the distance of the tunnel and foundation, obtaining analysis results with different surrounding rock conditions. The foundation overall tilt, foundation settlement, variation of stresses of adjacent high-rise buildings caused by the construction of new tunnel was studied thoroughly, and obtained some significant conclusions that can provide a reference for stipulation of control techniques for safety of adjacent buildings during construction of similar tunnels.
