| 摘 要： | 在尖湖桥施工监控中,采用有限元软件建立拱桥结构模型,分别对浇注拱肋混凝土、第一次张拉吊杆和成桥后三种状况下的拱肋进行受力分析计算,并与实际检测数据进行对比。结果表明,拱肋内混凝土刚度对模型结果影响较大;成桥后模型可以模拟拱桥的实际受力状态,并为施工监控提供理论支持。

| Abstract: | Based on the monitoring of Jianhu bridge,3-D finite element models were established with currently available software,and the force situations of the filling concrete,the first drawing suspender and the finished bridge were analyzed.The results indicate that the stiffness of concrete has a great affect on models.As a result,this model can simulate the practical status of the bridge,and can also offer a theoretical aid on monitoring. |
