大跨径连续刚构桥施工控制仿真分析

Simulation Analysis on Construction Control of Long-span Continuous Rigid Frame Bridges

连续刚构桥施工过程仿真计算是实施施工控制的基础,以某特大桥为工程背景,根据正装计算法理论,应用结构仿真技术和施工控制理论建立空间有限元模型对该桥进行施工过程仿真计算,对连续刚构桥施工仿真与控制进行了研究。

The simulation analysis on construction control of continuous rigid frame bridge is the foundation of the construction control. The simulation analysis and construction control of continuous rigid frame bridge is studied in detail,based on a continuous rigid frame bridge,according to the forward-calculating method. Then,a 3-D finite analysis model for the construction process of the continuous rigid frame bridge is established,with the theory of simulating analysis for the construction process.
