The subway station belongs to the underground reinforced concrete structure, and its overall construction idea is to first carry out the excavation of the foundation pit and then carry out the construction of the reinforced concrete structure of the station, and finally the earthwork backfill, because the bridge engineering has explained the concrete-related knowledge points very thoroughly, so the rail transit chapter has not carried out the construction of the main structure of the station, but the real questions over the years have repeatedly been raised in the construction of the station structure and the support and demolition of traffic construction, so here we will explain in detail, after the excavation of the station foundation pit is completed and the acceptance is qualified, the station floor is constructed firstIf the support hinders its construction when the side wall and the middle plate construction are carried out again, the support is removed first and then the construction of the side wall and the middle plate is carried out, and so on, the support that hinders the structural construction is first removed and then constructed, until the whole station structure construction is completed and the backfill is completed, if the foundation pit enclosure system has a column, then the column is removed after the station structure construction is completed, and if the position of the column is just the station structure position, the column does not need to be removed, After a solid understanding of this knowledge point, its similar deformation problems will be solved
