摘　　要：泄水闸坝坝顶门机梁是老口航运枢纽坝顶桥面关键构件,其特点是跨度大、承受荷载大、运行工况复杂。利用Midas Civil有限元软件对门机梁进行结构静力分析,拟定预应力门机梁结构形式、预应力钢束布置,为工程施工图设计提供依据。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-stressedtendon are proposed based on the structural static analysis on portal crane girder, which provides a basis for detailed design.
