摘要
各种大跨度桥梁的迅速发展使得对施工过程的仿真分析和控制日益重要。本文结合实际论述施工过程仿真的徐变计算问题，提出了时段划分和预拱度设置的新方法。所述方法已在南昆线清水河大桥等实际应用，证明正确方便。
The calculation methods for creep simulation of the PC bridge construction process are studied,the new methods for setting pre arched and dividing time steps are presented. Those methods had been actually used in Qingshui River Bridge of Naning Kunming Railway and proved to be correct and convenient.
