Abstract
Based on the Botanical Garden station of Xi'an Metro Line 8, the finite element analysis model of Pile-Beam-Arch excavation method(PBA) is established. Combined with the actual construction and geological conditions, the finite element simulation analysis was carried out according to different excavation sequences, and the settlement, deformation and stress behaviors under different working conditions were screened, and the displacement and stress characteristics of the guide tunnel excavated by the hole pile method under the multi-factor change effect were analyzed. The variation characteristics of the displacement and internal force of the whole system with different excavation processes are revealed, which provides an important reference for the design and construction of the PBA guide tunnel.
