摘要
以实际市政道路工程项目中分离式立交桥的设计与施工为依托,从主梁构造、钢束布置、基础型式、支承传力等方面介绍了斜腿刚构立交桥的设计原则和设计方法;并通过主梁、斜腿、基础阻滑体系的结构设计及有限元分析,阐述了斜腿刚构立交桥的结构计算方法。结合项目设计与工程实践,总结了斜腿刚构立交桥设计方法与优缺点,有关经验可供相关专业人员参考。
According to the design and construction of the separated interchange in the practical municipal road engineering projects,the article introduces the design principle and design method of inclined leg rigid-frame interchange from the aspects of main beam construction,steel beam layout,foundation type,support transmission and etc.And Based on the structure design and the finite element analysis of main beam,inclined leg and foundation anti-slip system,the article sets forth the structure calculation method of inclined leg rigid-frame interchange.Aiming at the project design and engineering practice,the article sums up the design method,advantages and disadvantages of inclined leg rigid-frame interchange.The relative experience can be referred for the similar projects.
