Simulation of 2D ground movement due to tunnel excavation using Finite Element Method (FEM)

Abstract Sustainability in construction of tunnel is very important to reduce environmental impact and also minimal use earth resources. Therefore, numerical modelling proposing at design stage achieved this objective. To evaluate the changes soil settlements during excavation, empirical, analytical, methods have been frequently applied movement research method effective anticipating possible underground excavation scenarios. This paper describes project on prediction 2D ground due by using Finite Element Method via ADONIS with properties data from certain section Goose Creek Tunnel project. The horse-shoe shape typically be 1.8 m wide 2.2 tall. However, paper, assumed as a circular diameter m. focus effects constitutive models. influence type model settlement investigated discussed. simulation confirmed comparing output manual calculation. findings prove Plastic Hardening (PH) more suitable excavation. By designing tunnelling structure low error, engineers can build most efficient tunnel.
