【摘要】 在公路、铁路等的立体交通工程中,地道桥被广泛地应用。为满足各种不同的实际要求,地道桥有着各种不同的结构形式、设计手段及施工方法。 本文按照地道桥的受力特点对其进行了分类,对其中两种主要结构的静力、动力特点进行了分析、比较和归纳;基于框架地道桥在不同斜交角度下的受力特征,对其结构设计提出了有用的建议;总结了地道桥的两类施工方法,并较详细地阐述了它们各自的主要过程;结合某地道桥设计计算实例,介绍了在结构设计方面的实用理论和方法。文中还提到了地道桥的设计、施工存在的一些问题,有待完善或进一步分析、总结。文章的内容较结合于实际,一些结论或建议包含了工作中传承或总结的经验教训。 本文较全面地讨论了地道桥结构的构造、设计和施工特点。对地道桥在实际工作中的应用,本文所提供的信息是有参考价值的。

【Abstract】 In the case of grade separation engineering for highway and railroad,underpass bridges are widely applied. For satisfying various different actual requirements,underpass bridges have the forms of various different structures,design means,and construction methods.The thesis classifies the underpass bridges according to their behavior characteristics,and static and dynamic behaviors of two main structures are analyzed,compared and concluded. Based on the behavior characteristics of underpass bridges with different skew angles some useful suggestions are then given for their design. Also,the construction methods of underpass bridges are summed up and each methods’ process is described in detail. Finally,a design case is enumerated,together with the introduction of practical design theories and methods.The structure,design and construction of underpass bridges are fully discussed in the thesis. The information involved would be helpful and valuable for application of underpass bridges.
