Summary:The invention provides a construction method of a laminated top longitudinal beam of a fabricated underground station. The construction method comprises the following steps that S1, a plurality of sections of prefabricated top plates are longitudinally spliced to the corresponding positions of a partial structure of the fabricated underground station; s2, a prestressed steel strand is tensioned and anchored at the top longitudinal beam prefabricated part; s2, building a downward turning part of the top longitudinal beam; s4, a top longitudinal beam prefabricated part at the position of the beam-column joint and a reserved steel bar of the middle stand column are staggered and mutually anchored, and UHPC is poured at the beam-column joint part to form a rigid joint; and S5, building an upturning part of the top longitudinal beam. The method is fast in construction progress and high in construction efficiency. When the covering soil of the station is thicker, the I-shaped steel is also inserted, so that the ben
