摘要
主要论述了涪江三桥施工控制的体系、方法、内容及实施过程,并分析了影响施工控制的主要因素和关键技术。在施工控制过程中,实测各项技术参数,与计算机有限元分析进行对比,最后给出施工控制参数,有效地调整桥梁的内力和线形,为提高桥梁施工质量和安全可靠提供科学保证。
This paper expatiates the system, technique, content and implying process of the third bridge across the Fujiang analyzes the main factors and key technique that affect construction control. In the process of construction control, measures technical parameters of construction control, compares it with finite-element analyzing results, and gives the parameters of construction control. This method effectively controls the internal force and linearity of bridge and ensures the onstruetion quality and safety.
