BSTunnelLining is a segmental tunnel lining analysis software program. The segments, joints, and surrounding ground are simulated with beams and springs using finite element method. BSTunnelLining can be used to analyze multi-ring segmental tunnel lining under arbitrary distributed and concentrated loadings. It presents the tunnel lining model and finite element model in 2D and 3D views.
BSTunnelLining presents the analysis results in the format of graphs and data tables. The graphs can be directly export to svg, png, and pdf file format. The data tables can be directly used in spread sheets. The results include segment moment, axial force, shear force, deformation, ground reaction, joint deformation and force and moment, and normal and tangential loads presentation.
