| description | The invention discloses a differential settlement control pre-propping excavation construction method for a deformation joint of an underpass subway station. The differential settlement control pre-propping excavation construction method comprises the five steps of deformation joint reinforcement, pre-construction, pilot tunnel primary reinforcement, pilot tunnel secondary reinforcement and working face construction. According to the construction method, the basic principle of a shallow tunneling method is followed in construction, so that the stress state of a long-term operation subway station structure is effectively improved; stable supporting structures are formed on the two sides of the deformation joint, so that differential settlement of the two sides of the deformation joint of the station is controlled; and meanwhile, compared with a traditional construction technology, the construction technology is effectively simplified, construction difficulty and construction cost are reduced, and accordingly c |
