大跨径预应力混凝土梁桥施工控制的现状与展望

State of Art and Prospection of Construction Control of Long Span Pre-stressed Concrete Beam Bridge

系统地回顾近年来大跨径预应力混凝土梁桥施工控制的工程实践,从施工控制总策略、施工控制关键问题、集成的施工控制系统等方面进行全面的总结和分析,展望结构体系、施工过程仿真的精细化研究、施工控制评价指标、施工误差容忍度等方面的研究前景。

Based on a review of construction control of long span pre-stressed concrete beam bridge in recent years,a systematic analysis and summary are presented in this paper,including the main strategy of construction control,the key point of construction control,and integration construction control system.Prospects about the structure capability,in-depth study of simulation analysis about construction process,the evaluation index of construction control,error criterion of construction control are also given.
