大跨度客运专线连续刚构桥后期徐变研究

Research on engineering creep in later period of continuous rigid frame bridge on large-span passenger special line

以某大跨度客运专线连续刚构桥为例,对常用规范徐变系数及徐变变形计算方法作了分析,并运用有限元软件对其后期变形计算作了论述,从而为准确预测桥梁后期变形奠定了基础。

Taking the continuous rigid frame bridge on some large-span passenger special line,the paper analyzes the creep coefficient of regular regulations and the calculation methods of the creep,and indicates the deformation calculation in the later period by using the finite elementary software,so as to lay the basement for expecting the bridge＇s deformation in the later period.
