新华立交桥加固前后承载能力对比分析

Study on Comparison of the Bearing Capability before and after Strengthening of Reinforced Xinhua Overpass

通过对加固前后的新华立交桥的检测结果进行比较,分析该桥在加固以后的承载能力及刚度变化情况,检验该桥的加固效果对桥梁耐久性及承载力安全储备的提高。从而看出定期检查对于桥梁承载能力的重要性,从检测结果分析病害原因,为加固设计提供依据。

Based on the comparison of the detected results of the before and after reinforced Xinhua Overpass, the article discusses the changing of the bearing capability and stiffness. And it tests the reinforcement effect of the bridge and improving of the bridge durability and bearing capability safety margin. The article discusses the importance of regular inspection of beating capability. It can provide basis to reinforcement design by analyzing disease causes.
