摘要：

In order to provide a basis for the reinforcement design and construction safety of the double-arch tunnel, it is of theoretical and practical value to analyse the morphological characterization, the evolution process and the skewed effect of the pressure-arch in a double-arch tunnel. Based on the descriptions of the boundary parameters of the pressure-arch in a double-arch tunnel, taking the 80 m buried depth double-arch highway tunnel as the research object, the numerical calculation model of the double-arch tunnel was built by using FLAC3D, and then the morphological evolution of the pressure-arch induced by step-by-step excavation was analysed. The results showed that the pressure-arch of the double-arch tunnel displayed the skewed distribution characteristics which were gradually diminishing from the left tunnel to the right tunnel, the strain energy dissipation of the double-arch tunnel from the left tunnel to the right tunnel was from high to low, and the nonlinear response characteristics in different excavation sequences were sensitive to the changes of the stress state. The results provided a basis for the rock reinforcement design and safety construction of double-arch tunnel. © 2016, Strojarski Facultet. All rights reserved.
