The invention discloses a construction method for building a subway station through combination of a subsurface excavation method and a shield driving method. The construction method comprises the following construction steps that S10, a shield driving work well is built, shield driving is conducted towards a station pre-arranged place, and segments are assembled; S20, subsurface excavation of corner end pilot tunnels is conducted on the upper portion of a shield driving channel according to the preset width of the station; S30, side edge support structures of the station are downwards built in the corner end pilot tunnels; S40, subsurface excavation of a plurality of top pilot tunnels is conducted on the upper portion of the shield driving channel according to the preset height of the station; S50, top support structures of the station are built through the top pilot tunnels and the corner end pilot tunnels; and S60, downward excavation is conducted through the corner end pilot tunnels and the top pilot tunnels, and the shield driving segments are broken. The problem of overall planning construction of the subsurface excavation station and a shield driving zone can be solved, overall planning control over the construction period is facilitated, the subsurface excavation construction risk and the segment breaking construction risk can be reduced, meanwhile, the building progress is accelerated, and the engineering quality is guaranteed.
