本文介绍用光弹性试验方法,借助弹性理论中薄板弯曲理论的假设,应用条纹倍增技术,分析斜交箱形框架桥的应力分布情况。实验结果用静力平衡方法校核误差较小,与用资料[6]的计算方法所得应力分布规律基本符合。由此可见,用光弹性试验方法可以得出较准确的数据,为斜交箱形框架桥的设计和理论分析提供比较可靠的依据。 In this paper, we introduce the method of photoelasticity test to analyze the stress distribution of skewed box-girder bridge with the help of the theory of strip bending in elastic theory. The experimental results using the static balance method to check the error is small, with the data obtained by the method [6] The distribution of stress is basically consistent. It can be seen that more accurate data can be obtained by the photoelastic test method, which provides a reliable basis for the design and theoretical analysis of the skewed box girder bridge.
