The invention discloses a multi-suspended-pylon cable-stayed bridge and aims to provide a bridge for constructing a larger span and is suitable for linking multiple bridges for constructing an over-long distance bridge or used for constructing an elevated trackway transportation system and more suitable for constructing a small and medium size bridge. The multi-suspended-pylon cable-stayed bridge comprises a plurality of branch spans with different heights, top cables 1, bottom cables 6 and force transmission cables 4, wherein the plurality of branch spans consist of suspended branch pylons 3 and are added in the middle part of the cable-stayed bridge; the top cables 1 are fixed to two main pylons 2 and the tops of all branch pylons and sagged in the shape of a fold line; the bottom cables are fixed to the root parts of all the branch pylons; the bottom ends of the force transmission cables are fixed to the bottom ends of all the branch pylons, and the top ends are fixed to the top of a closest branch pylon or a main pylon towards the direction of a closest main pylon; and the top ends of all stayed-cables 5, the bottom ends of which are uniformly fixed to a girder 6, are all fixed to the top of a closest branch pylon or a main pylon facing towards the direction of a closest main pylon.
