| 摘 要： | 对钢管混凝土桁架式拱桥中钢管及缀板腔内混凝土灌注时拱肋的受力特性进行了分析.分别采用了平面简化计算方法及空间有限元法对拱肋混凝土灌注过程中的应力进行研究,并在对比两种方法计算结果的基础上对简化方法的精度进行了评价.研究表明:在钢管内混凝土灌注时一般可满足受力要求；而在缀板腔内混凝土灌注过程中,钢管与缀板交界处以及缀板横...

| Abstract: | Mechanical characteristics of ribs in truss type concrete-filled-steel-tube(CFST) arch bridges are analyzed during concrete pouring in tubes and stiffer plates.Simplified calculation method and spatial finite element method are both applied to analyze stress distribution in ribs during the process of concrete pouring,and precision of simplified method is evaluated on the basis of results comparison.Results show that the requirements of structural stress are well met during the process of concrete pouring in... |
