| Abstract: | Three dimensional finite element method was applied in this paper to analyse the influence of deep excavation on adjacent viaduct foundation. The monitoring and the result of calculation are in good agreement, so the calculation model is reasonable. The computation result shows that the additional internal force of viaduct pile foundation caused by excavation is very small, so the technical method used in the construction could effectively controll the deformation of the excavation and reduce its influence on adjacent viaduct foundation. |
