摘要:
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。
Abstract:
The cable stayed concrete bridge is one of the advanced bridge types used for modern large span bridges.However,it is quite complicated for calculat- ing the creep in concrete during cantilever-construction.In this paper,a numerical method is suggested for calculating internal forces and creep defo- rmations in concrete during construction.The effects of shrinkage and the dead load are also considered,and the accurate results can be obtained by means of computer.
