The utility model discloses a stepped bridge for nuclear power. The ladder bars are fixedly connected below the side plates; the internal space of the bridge is not occupied; due to the cable-stayed reinforcing rib plates, the supporting strength is improved; the through holes in the ladder bars can be used for fixedly connecting the cable-stayed reinforcing rib plates; the device can also be usedfor binding and fixing a cable line; meanwhile, the inverted U-shaped structure of the ladder bar can also provide limit for the nut; the thicknesses of hot-dip galvanizing layers on the surfaces ofthe side plates, the ladder bars and the cable-stayed reinforcing rib plates are controlled to be 85-110 microns; the cable can meet the performance requirements of nuclear power engineering for highcorrosion resistance, high earthquake resistance and heavy load supporting, the service life is as long as 60 years, on-site cutting and welding are not needed, installation and connection operation is convenient, a cable line
