Abstract:
To study the influence of the reserved holes in the wall at L-shaped corner passage on the internal force of the metro station roof and floor, a case study is conducted on rehabilitation project of connection passage between Wuhoujie station on line S3 of phase 1 of Ninghe intercity railway and Zhengrong G64 block, and numerical simulation analysis is carried out on roof and floor of 3D solid model before and after opening using finite element program ROBOT. Conclusions are drawn as follows: (1) The bidirectional stress on the roof and floor at the corner of entrance/exit channel is larger when the sidewall of existing entrance/exit than no holes. (2) In the design stage, considering longterm development, the reinforcing bars at the corner is strengthened using bidirectional slab.
Key words: metro station, L-shaped corner passage, sidewall opening, structural transformation, numerical analysis, roof and floor reinforcement
