A method for assembling a gas turbine (1) having silo combustion chamber, in particular for assembling the hot-gas inner casing of said turbine, comprises the steps of: providing a hot-gas inner casing (11) of the turbine (1) with resting feet (21) provided with respective first holes (23) having a pre-set first diameter (D1); providing an outer casing (8) of the turbine (1) with brackets (20) provided with respective second through holes (33) having a second diameter (D2), greater than the first diameter (D1); positioning the inner casing (11) around a rotor (2) of the turbine (1) and hence in the outer casing (8), and resting the feet (21) on respective brackets (20); centring horizontally the inner casing (11) with respect to the outer casing (8); arranging fixing plates (34), provided with threaded seats (35) having substantially the first diameter (D1), underneath the brackets (20) on the side opposite to the feet (21); and screwing fixing tie-rods (24), which have substantially the first diameter (D1) and are inserted through the first holes (23) and the second holes (33) in respective threaded seats (35).
