装配式连续梁桥的设计与施工

Design and Construction of Assembly Continuous Beam Bridge

目前,在中小跨径桥梁的设计和施工中多采用先简支后连续箱梁和支架现浇连续梁,但这两种形式都有一定的不足。装配式连续梁桥是将预制梁与现浇梁相结合的全新结构形式,这种结构形式综合了其他两种形式的优点,弥补了它们的不足,是中等跨径梁桥设计与施工的新理念、新方法。

At present, the step of simply supported beam at first and the continuous box beam and support castin-place continuous beam after it is used in the design and construction of bridge with the small and medium span, but all these two forms have the certain insufficiency. The assembly continuous beam bridge is a new form of structure combining the precast beam with the cast-in-place beam, which synthesizes the merits of the other two forms and makes up their insufficiency. So it is a new idea and method in the design and construction of the beam bridge with the medium span.
