The invention discloses a double-track beam for magnetic levitation holding-rail type rail transit. The double-track beam comprises a left box beam body and a right box beam body which are erected on a bridge pier. The left box beam body and the right box beam body are of the same structure. The left box beam body is installed on the bridge pier through a left support, the right box beam body is installed on the bridge pier through a right support, and the left support and the right support are of the same structure; the right side of the left box beam body and the left side of the right box beam body are fixedly connected together through a horizontal beam, and the horizontal beam is integrally in a cylindrical shape and made of concrete filled steel tubes; the horizontal beam is arranged over the bridge pier, and a gap is formed between the horizontal beam and the bridge pier. According to the double-track beam, the left box beam body and the right box beam body are connected through the horizontal beam, the overall rigidity is greatly improved to be three times the rigidity generated when a left single beam and a right single beam are arranged separately, deformation generated in the structure stress process is correspondingly greatly reduced due to increase of structural rigidity, and the strict requirement for structural deformation of a maglev project is met.
