大跨度连续梁支架现浇施工控制技术

Large Span Continuous Beam Bridge Support Cast-in-Place Scaffold Construction Control Technology

本文从连续梁桥支架现浇施工的控制因素、不同桥梁的施工控制与质量控制等方面开展了混凝土浇筑桥梁施工技术的研究,提出了混凝土桥梁质量的防治措施与控制方法;利用自适应控制系统不断地修正设计参数,支架标高、支架结构稳定性,反算初始计算模型所选用的参数是否合理,对路桥连续梁支架现浇混凝土浇筑具有一定的指导作用。

From the continuous beam bridge support cast-in-place scaffold construction control factor and different bridge construction and quality control, it is conducted the research of pouring of concrete bridge construction technology and put forward the prevention measures and control methods of concrete bridge quality. Through the identification of the health system or parameter estimation, constantly correcting pa- rameters, the design output and the actual output match, the actual problem is controlled, which has a cer- tain instruction function to the highway bridge continual boom support cast-in-place concrete construction.
