A shell-spring finite element model of a special-shaped tunnel was established to investigate the distribution of internal forces and deformation mode of the lining at the designed buried depth. The numerical results were compared with prototype loading test results and uniform beam model, which showed that the shell-spring model can be an optimal model to calibrate the 3D distribution of the i…

Based on the mining case of Dafosi Coal Mine in Shaanxi Province, which is a typical coal mine with extra-thick coal seam, the effects of mining width, buried depth and rock grade on the ground surface deformation and sur-rounding rock stress have been studied by numerical experiments. It is found that both of the ground surface settlement (SS) and Horizontal Displacement (HD) increased with th…
