摘要
以某连续刚构桥为工程依托,通过模拟该桥悬臂浇筑与满堂支架两种不同的施工方法,研究了悬臂施工对连续刚构桥,在自重、预应力作用下的弯矩、剪力分布的影响,为同类桥梁的设计及施工提供了一定的借鉴意义.
This paper,based on a continuous rigid frame bridge,through the simulation of two different methods: cantilever casting and full space supports,studies the impact of cantilever construction on the bending moment and shear forces of continuous rigid frame bridge under dead load and prestressed.It can be used for reference meaning for the similar bridge s design and construction.
