摘要
结合广州某预应力混凝土T型刚构桥的病害情况,介绍了该旧桥的拆除工艺,并建立了全桥的三维仿真分析模型,计算了各拆除工况下桥梁结构的受力情况,保证了桥梁拆除施工的安全性。
Combining with the diseases on some prestressed concrete T-shaped stiff bridges in Guangzhou,the paper introduces the demolition crafts of the old bridge,establishes the three-dimension simulation analysis model of the bridge,and calculates the stressed status of the bridge structure under all kinds of demolitions,so as to ensure the safety of the bridge demolition.
