摘    要:因超大型U型渡槽横向刚度偏小 ,提出横向加肋的新型半椭圆薄壳渡槽 对此三向加预应力的新型中长壳渡槽 ,用梁理论计算 ,将会带来较大误差 ,本文用有限元法分两个阶段进行力学分析 ,认为单槽设计是可行的 可供有关工程设计参考

关 键 词:渡槽  预应力  有限元法

Abstract:Considering the defect of super U-type aqueduct, whose transverse stiffness is lower, a new semi-elliptical aqueduct, on which transverse ribs are set for every two-meter long, is presented For the three-dimensional prestressed aqueduct, design applying traditional beam-theory will lead obvious error Therefore a two-stage mechanics analysis applying FEA, is developed. For a single-duct design, this method is feasible. The results have referential value for similar engineerings
Keywords:aqueduct  prestress  finite element method
