| 英文摘要 | Yielding support is effective in controlling excessive deformation of soft rock in squeezing tunnel engineering, and the developed polyethylene (PE) pipe filled with foamed concrete is a good choice serving as a yielding support. To deal with distortions brought on by significant mesh deformations and to enhance visualization, a numerical simulation method based on finite element method-smoothed particle hydrodynamics coupling (FEM-SPH) is adopted taking into account the progressive failure of PE pipes filled with foamed concrete (FC-PE) during deformation. By simulating the gradual failure of foamed concrete through smooth particle flow and the wrapped PE pipe using the finite element method, the damage process of the filled pipe has been examined. Comparison with experimental results demonstrates the superiority of the proposed model in terms of computational efficiency and accuracy, investigating the impact of several critical variables on the energy absorption capabilities of FC-PE, as well as setting pertinent evaluation indicators based on practical engineering application conditions. Additionally, numerical results demonstrate that the frictional characteristics between PE pipe and foamed concrete have little effects on the deformation energy absorption properties. The numerical results also demonstrate that the FC-PE's diameter has a positive impact on both the energy absorption efficiency and the usage efficiency, while thicker FC-PE having a lower energy absorption efficiency. |
