钢管混凝土劲性骨架混凝土拱桥是一种典型的自架设方式施工的桥型,其施工过程是结构安全的重要控制点,且施工顺序和方式会影响到桥梁运营时的受力状态。本文以某上承式钢管混凝土劲性骨架混凝土箱型拱桥设计为依托,分别采用平面杆系模型和空间板、梁体系模型对桥梁的施工、运营进行一体化的计算分析,为同类型桥梁的设计、施工提供借鉴和参考。 The CFST arch bridge is a typical type of self-erecting bridge. The construction process is an important control point of structural safety. The construction sequence and mode will affect the state of the bridge during operation. In this paper, based on the design of a concrete-filled steel tube reinforced concrete box arch bridge, the integration and calculation of the bridge construction and operation are respectively carried out by the plane bar system model and the space plate and beam system model, Design, construction provide reference and reference.
