摘要

As urban rail transit (URT) continues to be rapidly constructed worldwide in response to strong public demand, significant impacts on the ridership of existing stations are being observed. This study focuses on potential disruptions caused by constructing a metro line that passes over a bus company building. In this paper, a finite element model was developed using Midas GTS NX, employing a stratigraphic-structural method to simulate the construction process. The study analyzes the effects of different reinforcement methods on the disturbances caused during construction. The findings indicate that isolation piles (or walls) are more effective at controlling vertical displacement in frame structures and pile foundations. At the same time, sleeve valve tube compensation grouting is superior at managing horizontal displacement. Additionally, isolation piles provide better control over maximum axial forces in columns, whereas sleeve valve tube grouting is more effective for managing maximum bending moments in beams.
