摘要
本文结合苏州新区高架桥现浇钢筋砼连续箱梁设计,介绍了现浇连续宽箱梁的布置方式、构造设计、受力分析以及施工方法,重点论述了宽箱梁及变宽箱梁的箱室布置,并对箱梁横向分布、横隔梁受力采用空间分析法和简化算法进行了对比计算,结果表明简化算法能满足工程设计的要求。
The paper introduces the disposal of on-site moulding continuous broad box girder,mechanics analysis and construction technics, combining the design of prestressed concrete on-site moulding continuous box girder overhead viaduct in Suzhou new district.lt undeclined the box room disposal of broad box girder and non-uniform width box girder,and space analytical method is compared with predigest calculation method in box girder transverse distribution and cross slab tress calculating, the results show that predigest calculation method satisfies the requriment of engineering design.
