| Abstract: | The displacement of the steel centering in the preliminary lining of the enormus crosssection of a tunnel in loess is measured with a dial gauge in situ and the stress of the steel centering is calculated. Meanwhile,a regressive analysis is made on the convergence measurement of the tunnel. The state of stress of surrounding rock and tunnel lining under different comstruction stages of the tunnel are analyzed with the two-dimensional elasto-plastic finite element method, the runnel lining is examined and the designing parameters of the tunnel are suggested. |
