预应力混凝土连续刚构桥合龙段劲性骨架研究

Research on Stiff Dramework of Closure Section of Prestressed Concrete Continuous Rigid Frame Bridge

讨论预应力混凝土连续刚构桥合龙段劲性骨架的作用及设置,并从多个方面研究了劲性骨架最小截面的确定方法。该方法与已有文献相比更准确且易于手算,为工程设计及校核提供了一种参考。

The paper discusses the function and setting of stiff framework of closure section of prestressed concrete continuous rigid frame bridge,and studies the confirmation method of the minimum section of stiff framework from various aspects.Compared with existing literatures,this method is more exact and easily calculated by manual labor,which provides a reference to the design and checking of engineering design.
