Investigation of ground vibration from circular tunnels using a 2.5D FE/BE model of tunnel and ground
Investigation of ground vibration from circular tunnels using a 2.5D FE/BE model of tunnel and ground
A numerical model of a circular tunnel using the 2.5D finite element and boundary element method is described. This makes use of the constant geometry in the axial direction so that a two-dimensional model is solved for a series of wavenumbers. The full 3D solution can be recovered by a Fourier transformation. The response of the tunnel structure is analysed first. Then, the vibration at certain points on the ground surface is predicted using the tunnel-soil model. Finally, a parametric study is carried out to show the influence of different aspects of tunnel design to the vibration in the ground.

Abstract
A numerical model of a circular tunnel using the 2.5D finite element and boundary element method is described. This makes use of the constant geometry in the axial direction so that a two-dimensional model is solved for a series of wavenumbers. The full 3D solution can be recovered by a Fourier transformation. The response of the tunnel structure is analysed first. Then, the vibration at certain points on the ground surface is predicted using the tunnel-soil model. Finally, a parametric study is carried out to show the influence of different aspects of tunnel design to the vibration in the ground.
