摘要
为了使斜拉桥在施工过程中的索力和线形能符合设计要求,对重庆忠县长江大桥斜拉桥主梁悬浇施工阶段全桥的线形和索力进行了控制,采用桥梁博士软件模拟斜拉桥施工过程,通过理论计算和实测数据进行对比、分析。数据表明,索力和线形基本符合设计计算值,并能确保桥梁施工的安全性。
In order to make cable-stayed bridge in the construction process cable pulling force and linear meet the design requirements, according to some content and method for cable pulling force and linear control during rotating cast construction of girder of large-span cable-stayed bridge in Changjiang River Bridge,this paper, by Dr. Bridge 3.1.0 version simulating construction process of cable-stayed bridge,compared and analyzed the theoretical calculation by software and the measured data showed that pulling force and linear can meet the basic design calculations by data and the safety of bridge construction was ensured.
