苏丹RUFA’A大桥的施工监控研究

Research on the Construction Control of RUFA’A Bridge

结合苏丹RUFA’A大桥的施工过程,综合考虑混凝土的徐变、收缩及温度等各种时效因素的影响,对RUFA’A大桥的长期变形进行仿真分析研究。通过跟踪模拟桥梁在整个施工过程中各个时刻的结构应力和结构变形,并结合施工现场的实测数据不断进行误差分析和参数修正,从而为下一阶段的施工过程提供更加合理的控制参数,达到工程控制的目的。

Combining with the construction course of RUFA＇A bridge, taking into account man） time-dependent factors such as the creep and shrinkage of concrete, the change of temperature and etc. the long term deformation of RUFA＇A bridge has been researched. By researching on the stresses and deformations of the bridge at any period of time during the whole construction sequences, and combining with the survey data obtained at the construction spot, the deviation analysis and parameter revise have been carried out constantly, by means of which the reasonable control data during the next construction stage can be determined, and the aim of construction control can be obtained.
