Abstract

Abstract

The excavation process of the tunnel construction in metro line No. 5 adjacent to Yuting Bridge in Beijing was modeled by 3D-ANSYS numerical code. The influence of the excavation on the bridge's platform and ground environment was analyzed. The computed results were compared with measured data. It is shown that the influence of the excavation on the bridge's platform andground environment is in the range of the allowable value following the design. Any additional prior consolidating measure is not needed.
