摘要
以忻州至保德高速公路K116+179天桥为例,介绍了上承式钢筋混凝土箱形拱桥的主要设计过程,为了合理拟定拱桥的重要尺寸,设计时采用通用桥梁博士软件对全桥进行了结构分析和计算。结果表明,该拱桥尺寸拟定合适,整体结构安全可靠,可为同类桥梁的设计提供参考。
Taking Xinzhou-Baode highway K116＋179 overpasses as the example,it introduces main design process of upper bearing reinforced concrete box arch bridge,carries on structural analysis and calculation by adopting commonly used bridge doctor software in the design in order to reasonably simulates the main size of the arch bridge.Results show that： the bridge simulation is suitable and the overall structure is safe and reliable,which has provided guidance for similar bridge design.
