摘要
本文通过对连续箱型梁桥控制截面和典型位置的应力和变形观测,得到了桥梁实际应力分布和变形情况。通过动载试验,得到了结构的频率等参数。结果表明,该桥理论分析和设计计算方法可靠,施工质量优良,桥梁刚度和承载能力满足要求。
in this paper, the situation of distribution of real stress and deformation of bridge beam were obtained through the observation of control cross-section and stress in typical position of continuous box bridge beam. The parameters of structure of frequency,etc.were taken by the test of live load. The results show that theoretical analysis and design calculation method are reliable, quality of construction is well and the stiffness and load capacity of bridge beam fulfill the requirement.
