Abstract：
Considering the structural characteristics and construction method of underground initial support multi-arch secondary lining independent interval structure tunnel of Beianhe Station, which is the origin station of Beijing subway line 16, key points for construction quality control were established on the aspects of measuring line paying off, middle wall position control, hole excavation size control, steel frame installation accuracy, end locking anchor pipe (rod), sprayed concrete strength, rear backfill grouting. Structural stability and construction safety were successfully guaranteed.
