description The invention discloses a transverse tunnel cover method for shallow-buried underground excavation large underground space construction. Foundation pits or pilot tunnels are formed, in the longitudinal direction of underground space, of the tops of side walls of the underground space to be constructed, temporary transverse stress structures are formed inside the foundation pits or the pilot tunnels at a time and located above a top plate of the underground space to be constructed and are controllable in rigidity, the temporary transverse stress structures are connected with piles inside the foundation pits or the pilot tunnels to form a temporary transverse top cover-pile bearing system, and under protection of the transverse top cover-pile bearing system, a single-span or multi-span and a single-layer or multi-layer underground space structure can be constructed in a sequential construction mode or in an inverse construction mode. In shallow-buried underground excavation large underground space structure construction, ground settlement is effectively controlled, constructed building deformation is reduced, the construction risks are reduced, the construction period is shortened, and the construction cost is lowered.
