混凝土斜拉桥是现代大跨径桥梁的先进桥型之一,由于具有采用悬臂法施工的突出优点,因而发展很快。但施工过程中的徐变计算是个十分复杂的问题,本文采用逐次数值计算法求解施工过程中混凝土徐变对结构变形和内力的影响,并考虑了混凝土收缩及桥上结构恒载的作用,借助于计算机得到较为精确的结果。 Concrete cable-stayed bridges are one of the most advanced bridge types for modern long-span bridges, which have developed rapidly due to their outstanding advantages in cantilever construction. However, creep calculation during construction is a very complicated issue. In this paper, successive numerical calculation method is used to solve the influence of concrete creep on the deformation and internal force of concrete during construction. The effect of concrete shrinkage and constant load on the bridge structure are considered In the computer to get more accurate results.
