ABSTRACT

The purpose of this research is that the analytical solutions of nonlinear behavior of ground in a deep circular tunnel under anisotropy stress field are derived, and the explicit analysis method (EAM) which bases on the convergence confinement method, the principle of convergence loss, and the simple calculation spreadsheet is particularly proposed. This study includes that introducing an incremental procedure of confinement loss into the analytical solutions derived under anisotropy stress field, establishing the direct calculation logic and flow chart, using a calculation spreadsheet to simply calculate and draw figures to describe the distribution of stress/displacement around tunnel. The results obtained by the explicit analysis and by the finite element analysis are approximately consistent in those curves described in the convergence-confinement method (CCM). The explicit analysis method proposed is easy and directly to simulate the ground response behavior due to the advancing excavation of tunnel. More... »

    25 schema:description The purpose of this research is that the analytical solutions of nonlinear behavior of ground in a deep circular tunnel under anisotropy stress field are derived, and the explicit analysis method (EAM) which bases on the convergence confinement method, the principle of convergence loss, and the simple calculation spreadsheet is particularly proposed. This study includes that introducing an incremental procedure of confinement loss into the analytical solutions derived under anisotropy stress field, establishing the direct calculation logic and flow chart, using a calculation spreadsheet to simply calculate and draw figures to describe the distribution of stress/displacement around tunnel. The results obtained by the explicit analysis and by the finite element analysis are approximately consistent in those curves described in the convergence-confinement method (CCM). The explicit analysis method proposed is easy and directly to simulate the ground response behavior due to the advancing excavation of tunnel.
