Portal crane girder on sluice dam crest is the key component of bridge deck on dam crest of Laokou navi-gation complex, which has large span, large load-carrying capacity and complicated operating conditions. By using of Midas finite element software, the structure of pre-stressed portal crane girder and the arrangement of pre-stressed tendon are proposed based on the structural static analysis on portal crane girder, which provides a basis for detailed design.
