【摘要】 结合工程实例,以国道312线柳忠—徐界高等级公路兰州段兰州东岗黄河大桥为工程背景,对不同温度梯度作用下,温度变化对箱形梁桥施工过程中不同阶段的应力和变形进行了模拟计算,通过分析和计算,得出了对大跨度桥梁施工控制有一定参考价值的结论.更多还原

【Abstract】 In this paper, takeing the Lanzhou Donggang Yellow River Bridge as engineering background, the construction process of different stages of the box girder in different temperature gradients is analyzed and calculated. With calculation and simulation, some meanmgful conclusions were drawn to longspan bridge construction control. 更多还原
