Background
The earthquake-resistant partition wall of the subway station is an important structural design, and has the functions of reducing the influence of the earthquake on the station structure when the subway station is in an earthquake and protecting passengers and facilities from being damaged. The shock-resistant partition wall generally adopts a reinforced concrete structure, and in the design of subway stations, the shock-resistant partition wall is usually arranged at key positions, such as pedestrian passages, surrounding platforms and the like.
