下承式钢管混凝土拱桥横梁结构试验研究

Structural Experimentation and Stress Analysis for the Crossbeam of Concrete-filled Steel Tubular Arch Bridges

通过对兰州市雁盐黄河大桥横梁进行现场监测,了解了该横梁在使用状态下的受力状况和应力水平;并对桥梁应力监测及分析方法作了介绍,该试验结果对于桥梁监控和同类工程有一定的参考价值.

Through the spot experimentation of the crossbeam of the Yanyan Yellow River Bridge, the performance of the crossbeam and its stress level under normal use were acquired. Stress monitoring and the analytical method were described in this paper. The results of the experimentation can act as references to the similar engineering.
