The invention relates to a coordinate calculation method for a module prefabricated slab of an ultrahigh-speed low-vacuum pipeline magnetic levitation traffic system, which comprises the following steps of: calculating the mileage of the center of a sleeve according to the parameters of the sleeve and the longitudinal gradient of a module prefabricated slab line after calculating the mileage of the starting point and the ending point of the module prefabricated slab, and further calculating the plane coordinate of a middle pile on a horizontal curve corresponding to the center of the sleeve according to the horizontal curve; the sleeve pile-in mileage is the same as the sleeve center mileage, according to the horizontal curve and the sleeve pile-in mileage, the sleeve pile-in tangential direction is calculated, then the sleeve pile-in normal direction is obtained, sleeve center coordinates are obtained through calculation, finally the sleeve center elevation is calculated, and sleeve three-dimensional coordinates are obtained through combination. The three-dimensional coordinate of the center point of each sleeve supporting face on the module prefabricated slab is calculated according to the module prefabricated slab endpoint mileage, the module prefabricated slab sleeve design parameters and the line horizontal and vertical curve, coordinate reference is provided for fine adjustment of the module prefabricated slab, coordinate calculation of the module prefabricated slab is achieved, the theory is strict, the result is accurate, and the automation degree is high.
