Modeling successive excavation within two dimensional finite element mesh
Original language description
The study presents a modification to conventional finite element method under plane strain conditions to address the problem of successive excavation of linear parts of tunnels. Although the successive excavation is a three-dimensional mechanical problem, the designers often prefer 2D analysis owing to considerably simple and transparent geometric model and fast computations when compared to a 3D solution. The main idea behind the suggested method referred to as, 2D3D model, is to express the influenceof excavation of a single stroke of soil not only in the particular cross section but in the entire soil body in front of and behind the examined profile.
