本设计的主要任务是依据新规范对悬链线箱形拱桥上部结构进行设计计算。作为桥梁的建造，前期的设计计算是必不可少的，这是施工的唯一客观依据，桥梁的安全系于此。本设计计算，将阐述箱形拱桥上部主要结构的受力分析和验算，可直接应用到施工设计中且具有一定的通用参考价值。
本设计计算完成的方法是根据老规范的计算示例的基本步骤而进行的，每一步骤都有可依据性。且依据新规范中的条例更改了已经不符合现今设计施工要求的方面，从而使用了大量时间去校对新老规范的异同之处。该设计计算结果是符合规范要求的，应用到现实施工中是可行、安全的。

The design of the main tasks was based on the new norms on the catenary arch bridge upper box structure design. Serve as a bridge to the construction, preliminary design is essential, which is the only construction objective basis, Bridge safety line. The design will be described in the upper box Arch major structural analysis and computation. can be directly applied to the design and construction of certain generic reference value. The completed design is based on the old standard calculation examples of basic steps, and that Each step can have sexual basis. And in accordance with the new norms of the change has not satisfied the requirements of the design and construction, thus used a lot of time to proofread the old and new norms of similarities and differences between the Department. The design is consistent with the results of the requirements, when applied to reality construction is feasible and safe. Keywords : catenary arch bridge upper box structure calculation
